Product details

HD-EFI Plug for 1.13mm Coax — 50 Ohm, 6 GHz

It delivers a 50 Ohm impedance path rated to 6 GHz, making it suitable for high-frequency signal interconnects in compact RF modules, antenna feeds, and test equipment where board space is tight. The snap-on fastening provides quick, secure mating without tools, and the gold-plated beryllium copper body and centre contact resist corrosion over repeated connect cycles.

Kit Contents and Cable Termination

This is a 4-piece kit: the connector body, a centre contact, a ferrule, and an insulator.

Mating Cycles and Field Service

The panel-mount configuration with snap-on retention suits applications where the connector stays fixed to a chassis and the cable is swapped during service — think test points, portable radio interfaces, or instrumentation panels.

Frequently asked questions

What is the impedance of the 920-512P-51S?

The 920-512P-51S is a 50 Ohm connector, the standard impedance for RF signal paths, ensuring matched transmission lines in most RF designs.

Is the 920-512P-51S compatible with 1.13mm cable?

Yes, the 920-512P-51S is designed for 1.13mm coaxial cable, as specified in the cable group. The kit includes the ferrule and insulator sized for that cable diameter.

What is the difference between HD-EFI and SMA connectors?

HD-EFI is a snap-on coupling interface, while SMA uses a threaded coupling. HD-EFI is typically smaller and faster to mate, but SMA offers higher torque retention and is more common in test and instrumentation. The 920-512P-51S is an HD-EFI plug and will not mate with an SMA receptacle.
