The 031-71058: This is the 75 Ohm variant of the standard BNC — the impedance is the first thing to confirm when matching to your cable and system, as a 50 Ohm plug will mate mechanically but create a mismatch that degrades return loss above a few hundred MHz.
Panel Installation and Termination
Mounts through a bulkhead panel and secures with a front-side nut — the threaded body and flange let you tighten from the accessible side, which is the standard arrangement for equipment enclosures where the rear of the panel is not reachable after assembly.
Temperature Range and Build Quality
The body is zinc die-cast with a nickel finish — the nickel provides corrosion resistance and a consistent surface for the bayonet lock to engage. The housing color is listed as silver and white, consistent with the nickel body and white dielectric insert visible at the mating face.
