KH-SSMAJW-SSMAK-RG1.37-60MM RF Cable Assembly: Ideal for High-Frequency Connections in Tight Spaces

In high-frequency electronic equipment, wireless communication modules, and various RF systems, cables may be relatively small components, but they play an important role in stable signal transmission and efficient internal device layout. This is especially true for compact electronic devices, where conventional RF cables with larger dimensions can be limited by installation space, bending radius, and connector orientation.

For applications that require short-distance, high-frequency signal transmission within a confined space, a compact RF coaxial cable with flexible connector configurations can make equipment design and assembly more convenient.

2. 60 mm Compact Design for Space-Constrained Connections

The Kinghelm KH-SSMAJW-SSMAK-RG1.37-60MM RF coaxial cable is designed for compact connection applications. With an overall length of only 60 mm, it uses RG1.37 black coaxial cable and features an SSMA right-angle male connector on one end and an SSMA female straight connector on the other, resulting in a compact and space-efficient assembly.

In wireless communication equipment, RF modules, test modules, embedded electronic devices, and similar products, internal installation space is often limited, while the distance between interfaces may be relatively short. Excessively long cables can make routing more difficult and may require additional looping, securing, or cable management.

The 60 mm cable length is well suited to short-distance connections and allows interfaces within a device to be connected directly according to their physical positions, helping simplify assembly and cable routing.

For electronic equipment designed with miniaturization and modularity in mind, a compact cable assembly can also reduce interference with surrounding components and occupy less valuable internal space.

3. SSMA Right-Angle Male and Straight Female Connectors for Flexible Installation

One of the key features of this product is its combination of two different SSMA connector configurations. One end is an SSMA male right-angle connector with a male pin, while the other end is an SSMA female straight connector with a female contact. Both connectors feature gold-plated contacts.

The right-angle design changes the direction in which the cable exits the connector. When space around an interface is limited, or when the cable needs to be routed along the edge of a device or parallel to a PCB, a right-angle connector can help reduce the space required for cable routing and provide greater installation flexibility.

The other end uses a straight SSMA female connector for connection to a corresponding SSMA male interface. The male-to-female configuration allows the cable to be used for specific RF interconnection requirements between compatible interfaces.

For R&D engineers, electronics engineers, and production technicians, selecting an appropriate connector configuration can help simplify internal RF cable routing and facilitate connections between modules.

4. RG1.37 Coaxial Cable for Compact High-Frequency Connections

The cable assembly uses RG1.37 black coaxial cable with an outer diameter of approximately 1.3 mm. Compared with larger-diameter coaxial cables, the RG1.37 format provides a more compact solution for applications where internal installation space is limited.

A coaxial cable typically consists of an inner conductor, dielectric insulation, and an outer shielding structure, forming a controlled transmission path for RF and high-frequency signals. Coaxial interconnection is widely used in RF modules, wireless communication equipment, and other high-frequency electronic systems.

For a short 60 mm connection, the small-diameter RG1.37 cable helps minimize the physical footprint of the cable assembly while providing a practical solution for internal RF interconnection.

5. Gold-Plated Connectors for RF Interconnection Applications

Both connectors are gold-plated. The SSMA female connector features a straight configuration with a socket contact, while the SSMA male connector features a right-angle configuration with a male pin.

As important components in an RF signal path, connectors must provide reliable mechanical mating and stable electrical contact. Gold-plated contact surfaces are commonly used in electronic connectors to support reliable contact performance and durability in appropriate applications.

The combination of SSMA connectors, RG1.37 coaxial cable, and a 60 mm overall length gives this cable assembly a compact form factor that is well suited to short-distance RF interconnections in space-constrained electronic equipment.

6. Black Heat-Shrink Tubing for Added Protection

The cable assembly is fitted with OD 2.5 × 1.5 mm black heat-shrink tubing.

The heat-shrink tubing is primarily applied around the transition area between the cable and connector, providing additional protection and helping reinforce the cable-to-connector interface.

For electronic equipment that requires installation, adjustment, or maintenance, maintaining the structural integrity of the transition area between the coaxial cable and connector is important for reliable cable management.

The black heat-shrink tubing matches the black RG1.37 coaxial cable, giving the assembly a clean and consistent appearance. Its compact size and black finish also make it convenient for organized internal cable routing.

7. 300 V Rated Voltage for Applicable Equipment Connections

This model is specified with a rated voltage of 300 V. When selecting a cable for a particular application, the actual operating voltage, frequency, power level, interface specifications, and other system requirements should be considered together. The rated voltage alone should not be used to determine whether the cable is suitable for a specific RF system.

For RF equipment, connector type, cable specification, connector configuration, installation dimensions, and other mechanical and electrical parameters are also important considerations. Engineers should therefore evaluate the complete system requirements when designing an RF interconnection solution.

8. Suitable for Short-Distance Connections Inside Electronic Equipment

With its 60 mm cable length, approximately 1.3 mm cable diameter, and right-angle male connector, the KH-SSMAJW-SSMAK-RG1.37-60MM is particularly suited to RF interconnection applications where installation space is limited.

Potential applications include wireless communication equipment, RF modules, communication terminals, test and measurement equipment, embedded electronic devices, and other products that use compatible SSMA interfaces. Depending on the specific interface layout, the cable can be used for short-distance RF connections between modules or between RF interfaces inside a device.

For designs with limited PCB space or closely positioned interfaces, the 60 mm cable length can help reduce excess cable while the right-angle male connector provides greater flexibility in cable routing and allows the assembly to better conform to the internal mechanical structure of the equipment.

9. Conclusion

As modern electronic equipment continues to become smaller and more highly integrated, connectors and cable assemblies must also adapt to increasingly compact internal layouts.
