JC3.660.3322 FME-C-KH155-1
Content
The FME-C-KH155-1 is categorized as an FME connector for flexible cable. Its product designation indicates a connector configuration intended for integration with a flexible coaxial cable assembly. Because the exact cable preparation, contact arrangement, plating specification, and dimensional details should be confirmed against the applicable product drawing, buyers should treat the product code as the starting point for technical verification rather than as a substitute for a complete engineering specification.
In a typical FME cable assembly, the connector consists of a center contact, dielectric support, outer conductor interface, connector body, and a cable retention or termination structure. Each part contributes to the overall performance of the finished assembly. The center contact carries the RF signal, the dielectric maintains the designed relationship between the inner and outer conductors, and the outer conductor provides shielding and the return path. The body supplies mechanical support and enables the connector to mate with a compatible FME interface.
The FME-C-KH155-1 is particularly relevant when a flexible coaxial cable must be routed through a confined space or connected to a compact wireless device. Flexible cable can be bent around equipment panels, vehicle structures, instrument housings, and communication modules. A connector designed for this cable type helps create an integrated assembly rather than requiring a bulky transition between dissimilar connection systems.
For applications involving high-frequency signals, connector geometry is critical. Small variations in contact position, dielectric support, conductor engagement, or shielding continuity can influence insertion loss, return loss, impedance stability, and signal reflection. A precision manufacturing process is therefore essential even for a compact connector. The connector must be produced with controlled dimensions and assembled consistently so that its RF performance remains predictable from one batch to the next.
The FME interface is commonly selected for compact RF systems because it combines a relatively small form factor with practical threaded mating. The threaded connection provides a positive mechanical engagement and helps reduce the risk of accidental separation caused by vibration or cable movement. This is useful in vehicle communication systems, portable equipment, and installations where the cable may be handled during maintenance.
A compact interface also makes it easier to design equipment with a higher connection density. When several RF cables must enter a housing, large connectors can consume valuable panel space and restrict cable routing. An FME connector can help engineers preserve room for other electrical, mechanical, or thermal components. The smaller format may also reduce the weight and bending load imposed on the cable assembly.
The FME format is often associated with flexible coaxial cable assemblies that connect antennas, modems, routers, wireless terminals, GPS or navigation equipment, and communication modules. In these applications, the connector is not an isolated component. It is part of a signal chain that may include an antenna, cable, adapter, surge protection device, bulkhead interface, and RF equipment. Compatibility across the complete chain is necessary to achieve the intended system performance.
When specifying an FME connector, designers should evaluate the mating interface, cable type, operating frequency, impedance, installation method, environmental conditions, and required service life. The FME-C-KH155-1 can be considered where these requirements align with the product’s technical configuration and approved cable compatibility.
The main practical advantage of an FME connector is its compact structure. The FME-C-KH155-1 can help equipment designers reduce the space required for cable termination and mating. This is especially helpful in wireless terminals, embedded communication devices, vehicle electronics, monitoring equipment, and other products where every millimeter of installation space matters.
A compact connector can also simplify the physical arrangement of a cable harness. Shorter routing paths may reduce unnecessary bends, support more orderly internal assembly, and make it easier to position cables away from heat sources or moving components. In a high-density enclosure, a smaller connector may allow additional ports, improved airflow, or more flexible placement of circuit boards and shielding structures.
The threaded FME coupling concept supports a secure mechanical connection. Unlike an interface that depends only on friction or a simple push-fit action, a threaded connection can be tightened to maintain contact pressure during normal vibration and handling. This characteristic is valuable in mobile and vehicle-mounted environments, where cable movement can gradually weaken less secure interfaces.
Reliable mating also supports maintenance efficiency. A technician can identify, disconnect, inspect, and reconnect the cable using a familiar threaded procedure. When the correct mating parts and torque practices are used, the connection can provide repeatable mechanical engagement over the intended service life.
Flexible coaxial cable is selected when routing adaptability is more important than the rigidity associated with semi-rigid or rigid cable. The FME-C-KH155-1 is categorized specifically for flexible cable, making it relevant to assemblies that must bend around equipment structures or follow a changing installation path.
Proper cable compatibility remains essential. A connector that is suitable for one flexible cable construction may not be appropriate for another cable with a different jacket diameter, braid arrangement, dielectric, or center conductor. The cable and connector must therefore be matched according to the manufacturer’s assembly instructions and technical documentation.
A coaxial connector maintains a controlled signal path through the center conductor and surrounding shield. When the contact geometry, dielectric position, and outer conductor interface are manufactured accurately, the finished assembly can help preserve signal integrity. This supports stable communication links and reduces the risk of performance variations caused by poorly fitted or inconsistently terminated components.
Stable RF performance is influenced by many factors, including connector quality, cable selection, installation technique, mating condition, environmental exposure, and system frequency. The FME-C-KH155-1 provides a practical interconnection platform, while system designers must verify that the complete assembly meets the required electrical targets.
The product can be considered for a wide range of RF applications. Potential uses include antenna cable assemblies, vehicle communication systems, wireless routers, cellular signal equipment, navigation devices, test equipment, remote monitoring products, industrial wireless systems, and compact RF modules.
Its application flexibility is strengthened when the manufacturer can provide related adapters, cable assemblies, lightning protection products, reverse polarity connectors, and other RF components. A broader product portfolio makes it easier for customers to create compatible signal chains from a single experienced source.
Choosing an RF connector requires balancing size, connection method, cable compatibility, performance requirements, installation conditions, and cost. The FME-C-KH155-1 may offer advantages over larger or less suitable alternatives when a compact threaded interface for flexible cable is required.
| Evaluation factor | FME-C-KH155-1 | Larger coaxial connector types | Non-threaded compact interfaces |
| Space requirement | Compact and suitable for restricted installation areas | May require more panel and routing space | Often compact, depending on design |
| Mating method | Threaded engagement for secure connection | Often threaded, but with a larger envelope | May rely on push-fit or snap-fit retention |
| Cable application | Designed for compatible flexible coaxial cable assemblies | May be optimized for larger or less flexible cables | Depends on the individual product family |
| Installation flexibility | Well suited to compact equipment and routed cable harnesses | Can be less convenient in dense assemblies | May be quick to install but requires suitable retention |
| Typical selection advantage | Balanced compactness, mechanical security, and RF interconnection | Higher robustness or power capability in some applications | Fast mating in applications where vibration resistance is adequate |
This comparison does not mean that one connector family is universally better than another. Larger connector types may be preferable for higher power, harsher mechanical loads, or larger cable constructions. Push-fit interfaces may be suitable where rapid service access is the priority. The strength of the FME-C-KH155-1 is its balance: it offers a compact format while retaining the practical benefits of a threaded coaxial connection.
Compared with a connector selected only for its low purchase price, a properly manufactured FME connector may provide better long-term value through more consistent assembly, reduced rework, fewer intermittent faults, and easier integration with compatible RF components. The total cost of ownership should include installation labor, inspection, maintenance, field replacement, and the consequences of signal degradation.
The performance of an RF connector depends heavily on manufacturing control. A connector may appear simple from the outside, but its internal dimensions and material interfaces directly influence the electrical and mechanical behavior of the finished assembly. Yangzhou Jingcheng Electronics Co., Ltd. combines product development, production, sales, and technical service within a specialized RF manufacturing organization.
Founded in 1999, the company has developed experience in the design and manufacture of RF coaxial connectors and related products. This long-term focus provides a foundation for understanding connector geometry, cable termination, shielding continuity, contact reliability, and application-specific requirements.
Experience is particularly valuable when customers require a product that must fit an existing cable, enclosure, antenna, or communication module. Instead of treating every connector as an isolated commodity, an experienced RF manufacturer can review the complete interconnection requirement and recommend a compatible configuration.
The company offers more than 2,000 product types. Its portfolio includes coaxial connectors, adapters, reverse polarity connectors, coaxial lightning protectors, high-frequency cables and cable assemblies, attenuators, terminal loads, antennas, and related RF components.
This breadth provides several advantages. Customers can source complementary components from one supplier, reduce the risk of incompatible interfaces, simplify technical communication, and coordinate product development more efficiently. It also enables the manufacturer to understand how a connector will function within a broader RF chain.
RF connectors require controlled production of metallic components, insulating supports, contact elements, and external shells. Precision machining, forming, stamping, plating, and assembly processes may be used according to the specific component design. The objective is to maintain dimensional accuracy, surface quality, contact alignment, and repeatable mating behavior.
For the FME-C-KH155-1, dimensional control is important in areas such as the center contact, dielectric support, threaded body, cable termination region, and outer conductor interface. Even small deviations can affect assembly consistency or electrical performance. Controlled tooling and inspection help reduce these risks.
The company reports the use of advanced manufacturing and testing equipment. In RF connector production, equipment capability is valuable only when supported by appropriate process standards, trained operators, inspection plans, and corrective-action procedures. The combination of machinery and process discipline helps establish repeatable production results.
Testing may include dimensional inspection, visual examination, mechanical mating evaluation, continuity checks, insulation verification, and RF performance testing as required by the product and customer specification. The exact test program should be confirmed for the FME-C-KH155-1 order, especially when the connector is part of a qualified cable assembly or regulated communication product.
A rigorous quality system supports consistency from incoming materials through final shipment. Important control points can include raw material verification, plating inspection, first-piece approval, in-process checks, assembly monitoring, final inspection, and batch traceability.
Process control is particularly important for connectors because many failures are caused not by an obvious design error but by variation. Examples include inconsistent crimp dimensions, incomplete shielding contact, damaged plating, incorrect dielectric placement, excessive center-contact movement, or insufficient mechanical retention. A structured quality system helps identify these issues before products reach the customer.
Engineering capability is another important strength. The company maintains professional R&D and engineering teams that support standard products, customized designs, and specialized interconnection solutions. This support can be useful when a customer needs cable compatibility confirmation, drawing review, packaging changes, custom labeling, or a modified connector configuration.
Engineering collaboration can also improve the manufacturability of a proposed cable assembly. A design may work in principle but be difficult to terminate consistently at production volume. An experienced connector engineer can suggest changes to cable preparation, tooling, strain relief, tolerances, or assembly sequence to improve yield and reliability.
Vehicles often contain limited installation space and expose cables to vibration, movement, temperature changes, and maintenance activity. A compact threaded connector for flexible coaxial cable can be useful for antenna and communication assemblies routed through dashboards, roof structures, equipment compartments, or control modules.
In this environment, cable routing should avoid sharp bends, excessive pulling force, and contact with hot or moving parts. The FME-C-KH155-1 can support the connection requirement, but the finished assembly should also include suitable strain relief and protective routing practices.
Wireless routers, gateways, modems, and communication terminals often use external or internal antennas connected by compact coaxial cable. Space constraints inside the housing make a small connector format valuable. The FME-C-KH155-1 may be considered for cable assemblies that connect RF modules to antennas, bulkhead interfaces, or protective devices.
System designers should confirm impedance, operating frequency, cable attenuation, connector orientation, and mating compatibility. In higher-frequency applications, the connector and cable assembly should be evaluated as a complete RF component rather than selected independently.
Navigation and positioning systems depend on reliable antenna connections. An intermittent coaxial interface can create signal loss, unstable reception, or difficult-to-diagnose system behavior. A properly assembled FME connection can provide a compact and serviceable link between a navigation antenna and its receiving equipment.
Where equipment is installed outdoors or in exposed locations, environmental sealing and protection become essential. The connector itself should be used with the appropriate cable jacket, sealing method, and enclosure design for the installation.
Industrial monitoring, automation, remote control, and sensor systems may use RF links across factories, warehouses, energy facilities, and infrastructure sites. These installations can involve electrical noise, vibration, dust, temperature variation, and repeated maintenance. A reliable coaxial connector contributes to the stability of the antenna and radio connection.
For industrial systems, engineers should consider not only connector performance but also cable support, grounding strategy, surge protection, and maintenance access. Coaxial lightning protectors and related products from the same product portfolio may be relevant where the installation is exposed to transient events.
Test equipment requires repeatable connections because inconsistent mating can affect measurement results. The compact FME format may be useful in portable instruments, signal monitoring systems, and specialized RF test assemblies where space and cable flexibility are important.
Repeated mating cycles should be considered when selecting the connector. Proper cleaning, inspection, alignment, and controlled tightening can help preserve interface condition and measurement consistency.
Correct assembly is necessary to obtain the intended performance from the FME-C-KH155-1. The connector must be matched to the correct flexible coaxial cable and terminated using suitable tools and procedures. Improper cable preparation can damage the dielectric, deform the braid, expose the center conductor incorrectly, or prevent the connector from achieving full mechanical engagement.
Before assembly, the cable should be checked for the correct outside diameter, conductor construction, dielectric type, jacket material, and shielding arrangement. The connector should be checked for visible damage, contamination, plating defects, and compatibility with the intended mating component.
Cable stripping dimensions should follow the approved technical drawing or assembly instruction. The center conductor and braid must be prepared accurately so that the signal contact and outer conductor interface are positioned correctly. Excessive stripping can reduce shielding performance, while insufficient stripping can prevent full insertion.
During termination, the cable should be kept straight and supported. Twisting or pulling the cable while the connector is being installed may place stress on the center contact or weaken the outer conductor connection. If crimping is required, the correct die and calibrated tool should be used. If soldering is specified, heat must be controlled to avoid damaging the dielectric or cable jacket.
After assembly, inspection should confirm that the connector is fully seated, the cable is retained securely, the center contact is correctly positioned, and no braid strands or conductor fragments can cause a short circuit. Electrical continuity and insulation checks may be performed before the assembly is installed in equipment.
When mating the connector, the two interfaces should be aligned without cross-threading. The coupling nut should be tightened according to the recommended method. Excessive force can damage threads or internal components, while insufficient tightening can lead to poor contact stability. The cable should not be used as a lever to rotate the connector.
Several factors determine the long-term reliability of the FME-C-KH155-1 in service. The first is material quality. Conductive components should provide suitable conductivity, mechanical strength, and resistance to the intended environment. Plating selection affects contact stability, corrosion resistance, and mating durability.
The second factor is dimensional consistency. The center contact must remain correctly aligned with the dielectric and mating interface. The outer conductor connection must provide continuous shielding and sufficient mechanical retention. Dimensional inspection helps prevent variation that could otherwise produce intermittent performance.
The third factor is assembly quality. Even a well-designed connector can fail if the cable is stripped incorrectly or the termination tool is unsuitable. Manufacturing instructions, operator training, and process inspection are therefore essential for volume production.
The fourth factor is environmental suitability. Temperature, humidity, salt exposure, vibration, dust, chemicals, and ultraviolet radiation can influence the cable and connector. Customers should verify the applicable environmental ratings and use additional sealing or protective measures where necessary.
The fifth factor is system-level design. Connector performance cannot compensate for an unsuitable cable, poor grounding, excessive cable bending, inadequate strain relief, or incompatible mating hardware. The best results come from evaluating the connector as part of the complete RF interconnection system.
Different customers may require different cable lengths, labeling methods, packaging formats, connector orientations, cable types, or assembly processes. The company’s engineering and manufacturing capabilities support standard, customized, and specialized interconnection solutions.
Customization may involve a cable assembly using the FME-C-KH155-1, a related adapter, a different cable length, a specific termination method, or integration with a coaxial lightning protector. Before requesting a customized solution, customers should provide the operating frequency, impedance, cable model, environmental conditions, mating connector, required quantity, drawing requirements, and inspection criteria.
For new product development, early technical communication can reduce delays. A manufacturer can review the proposed interface, identify cable compatibility concerns, recommend assembly methods, and confirm whether existing tooling is appropriate. This is particularly useful when the connector will be installed in large quantities or incorporated into an equipment qualification program.
Production planning should also consider sample approval, pilot assembly, first-article inspection, batch consistency, packaging, and traceability. These steps help ensure that a customized connector assembly performs consistently after it moves from development into regular production.
Before ordering the FME-C-KH155-1, buyers should confirm the complete technical requirement rather than relying only on the product name. The following checklist can help organize the inquiry:
| Requirement | Information to confirm |
| Product identity | JC3.660.3322 and FME-C-KH155-1 |
| Connector family | FME connector for flexible coaxial cable |
| Cable compatibility | Cable model, diameter, dielectric, jacket, conductor, and shielding structure |
| Electrical requirements | Impedance, frequency range, insertion loss, return loss, and insulation requirements |
| Mechanical requirements | Mating interface, installation space, retention, and expected mating cycles |
| Environmental requirements | Temperature, humidity, vibration, corrosion, sealing, and outdoor exposure |
| Production requirements | Quantity, sample approval, assembly tooling, inspection, packaging, and labeling |
| Documentation | Product drawing, test report, material information, and quality records as required |
Confirming these points early helps prevent the common problem of ordering a connector that fits physically but does not match the cable or electrical requirements. It also allows the manufacturer to recommend the most appropriate related products when an adapter, lightning protector, or cable assembly is needed.
RF connectors are often small, but they can have a significant effect on the reliability of an entire communication system. An experienced manufacturer can provide more than a catalog part. It can offer product knowledge, application guidance, quality control, production continuity, and engineering support.
