Product details

The 031-70237: Rated to 3 GHz maximum frequency with a 0.2 dB insertion loss, this plug suits 75 Ohm video, broadcast, and data-signal paths where signal integrity matters up into the low microwave range.

It remains available through the independent distribution channel for existing BOM lines, but new projects should select a current-production 75 Ohm BNC plug from the Amphenol RF catalogue. No official direct-replacement order code is listed; sourcing is per RFQ against the remaining factory and distributor inventory.

Termination Checklist — Crimp, Don't Solder

The kit includes one contact and one ferrule — order additional kits for multi-position runs. The centre contact crimps onto the signal conductor; the ferrule crimps over the braid and jacket. No soldering iron needed, which speeds field installation and avoids heat damage to the PTFE dielectric. Mates with any standard 75 Ohm BNC jack (female) with a bayonet lock.
