1.0/2.3 Plug for 75 Ohm Coax — Cable Group and Kit Contents
The Amphenol 282138-75 is a 1.0/2.3 series plug, male pin, built for 75 Ohm coaxial cable. It ships as a 3-piece kit: the connector body, a crimp contact, and a ferrule. The 1.0/2.3 interface is smaller than a standard BNC — common in dense video distribution panels and telecom equipment where board space is tight. Impedance is 75 Ohm, not 50, so it belongs on a video or data line, not an RF test bench.
Cable Match — Which RG Types Fit
This plug is specced for RG-122, 180, 180A, 180B, 195, and Belden 1855 and 1865A. Shield and contact both terminate by crimp.
Mating Half and Mounting
The 282138-75 is a free-hanging (in-line) plug with a push-pull fastening mechanism. It mates with the 1.0/2.3 receptacle, such as the 282133-75 bulkhead jack. That sibling is a gold-plated, solder-terminated receptacle with a front-side nut for panel mounting. The push-pull latch is quick to engage and release — suited for front-panel patching where you don't want to spin a coupling nut. 500 mating cycles cover regular re-patching in a control room or head-end rack.
