The 031-5137: This plug accepts RG-58, 58A, 58B, 58C, 141, 303, LMR-195, and Belden B7806A and 9907 — the standard 50 Ohm flexible and semi-rigid coax sizes that share a common dielectric diameter. The contact termination is push-on (solder or crimp the centre pin to the conductor), and the shield is secured by the twist-on body. No special tooling beyond a centre-pin crimp tool and a cable prep knife is required for field installs.
Construction and Duty
The dielectric is PTFE, which gives the wide temperature range and stable RF performance.
