Product details

75 Ohm 1.0/2.3 Receptacle for Video and Data Links

The Amphenol RF 282134-75 is a 1.0/2.3 receptacle, female socket, built for 75 Ohm systems — the impedance that sets it apart from the more common 50 Ohm 1.0/2.3 variants. Rated to 3 GHz, it covers the bandwidth needed for serial digital video (SDI), baseband video distribution, and high-speed data links where 75 Ohm is the line standard. The gold-plated brass body and beryllium copper center contact, both gold plated, support 500 mating cycles without signal degradation.

Mounting and Termination — Bulkhead Fit with Solder Center

Both the connector and the mounting nut ship together as a 2-piece kit.

The 75 Ohm impedance and 1.0/2.3 interface are the two specs that lock the BOM line — confirm the mating plug is also 75 Ohm before committing.

Frequently asked questions

Is 282134-75 compatible with RG59 cable?

RG59 is a 75 Ohm coax, which matches the 75 Ohm impedance of this receptacle. The center contact terminates via solder cup — the cable center conductor must be soldered, not crimped. Confirm the cable diameter fits the panel cutout and the shield termination method (solder to body) matches your assembly process.

Is 282134-75 equivalent to an SMB connector?

No — this is a 1.0/2.3 interface, not SMB. The 1.0/2.3 has a different shell diameter and coupling mechanism (push-pull vs snap-on for SMB). They are not mechanically interchangeable.
