The Premier Cable RG142 SMA right-angle female to FAKRA Z water-blue female RF coaxial cable is a customized interconnection assembly developed for automotive electronics, RF communications, and antenna systems.

One end features an SMA right-angle female connector, while the other uses a water-blue FAKRA Z female connector. The two interfaces are joined by silver-plated, double-shielded RG142 RF coaxial cable, providing a pre-assembled connection option for compatible RF equipment.

The conductor, dielectric, and shielding layers of the RG142 coaxial cable form the RF transmission path. A double-shielded construction can help control the effects of external electromagnetic interference, although the final shielding performance also depends on the exact cable construction, termination process, and connector installation quality.

The SMA right-angle female connector provides an alternative cable exit direction near the equipment port. The FAKRA Z female connector features a water-blue coded housing for identifying the corresponding automotive RF interface configuration. Together, these features allow engineers to evaluate RF connections and harness routing in compact equipment layouts.

This is a finished RF coaxial cable assembly connecting two different RF interfaces through RG142 coaxial cable. Its configuration is as follows:

Connector 1: SMA right-angle female (SMA jack).
Connector 2: FAKRA Z water-blue female.
Cable: Silver-plated, double-shielded RG142 RF coaxial cable, subject to project specification.
Product type: Customized RF coaxial cable assembly.
Key characteristics: Right-angle interface, RF interconnection between different connector types, and double-shielded coaxial construction.

Both the SMA right-angle female and FAKRA Z female configurations require mating-interface verification.

What Does This Product Do ?

Connects Different RF Interfaces

This cable can connect RF modules, antenna assemblies, and communication equipment with compatible mating interfaces. SMA and FAKRA use different mechanical interface designs, and a pre-assembled coaxial cable provides a defined connection path between such devices.

The assembly provides a physical RF connection; it does not automatically convert communication protocols or change signal frequency.

Accommodates Compact Installation Layouts

The right-angle SMA connector changes the cable exit direction near the interface, allowing engineers to evaluate installation options in confined spaces. Before use, verify the connector orientation, physical dimensions, clearance from adjacent components, and the minimum bend radius of the RG142 cable.

Product Knowledge

◆ What Is the Role of Double Shielding in an RF Cable ?

Coaxial cables generally use an outer conductor as a shielding structure to reduce the influence of external electromagnetic fields on internal signal transmission. A double-shielded construction typically contains two shielding layers, providing additional shielding design options for specific applications.

However, double shielding does not mean complete immunity to all interference. Actual performance also depends on shielding materials, braid coverage, grounding continuity, connector termination, and operating frequency.

When purchasing RG142 double-shielded RF cable, review the cable manufacturer's construction data and verify the finished assembly's shielding performance against system requirements.

◆ Does RG142 Alone Determine the Cable's Maximum Frequency ?

The RG142 cable designation alone does not establish the maximum operating frequency of the finished assembly. Although the cable has its own electrical characteristics, complete-assembly performance is also affected by length, connectors, termination processes, and test conditions.

For a specific communication band, review the cable datasheet and both SMA and FAKRA connector specifications. Confirm insertion loss, return loss, or VSWR as required by the system.

Product FAQ

Why Does SMA Connector Gender Matter ?

SMA connector gender is generally identified by the center-contact and interface construction, not by external threads alone. Purchasing checks should include the center contact, threaded mating interface, connector orientation, and mounting construction.

This product uses an SMA right-angle female connector, so the equipment side must have the corresponding mating interface.

Why Choose RG142 Instead of Another Coaxial Cable ?

RG142 can be selected for specific RF projects. Whether it is preferable to another coaxial cable depends on operating frequency, attenuation requirements, outer diameter, bend clearance, temperature conditions, and cost targets. Compare actual cable specifications rather than relying on the model designation alone.

Is This Cable Suitable for Automotive Use ?

It can be evaluated for automotive RF interconnection projects with compatible interfaces. Suitability for a specific vehicle or in-vehicle system requires confirmation of operating temperature, vibration conditions, cable durability, connector requirements, and customer validation standards. The FAKRA interface or RG142 designation alone does not establish automotive-grade certification.

Does Premier Cable Offer Wholesale and OEM Services ?

Premier Cable can evaluate connector integration, custom cable assemblies, OEM manufacturing, and volume procurement according to project requirements.
