Product details

BNC Plug for RG-58 — Field-Termination Kit

The 31-5800: This is the connector you reach for when terminating RG-58 plenum, Belden 88240, or 89907 cable — the cable groups are listed right on the spec.

Crimp Termination — Field-Ready

That means a clean, repeatable termination in the field with a standard crimp tool — no solder iron needed. The zinc die-cast body with nickel finish holds up to the crimp cycle without cracking. Rated for 500 mating cycles, so it's built for test leads or equipment that gets connected and disconnected regularly.

Temperature and Build Quality

That covers outdoor enclosures, unheated equipment rooms, and industrial floor conditions. The silver housing color is standard for nickel-plated BNCs — easy to spot on a crowded patch panel.
