Product details

BNC jack for LMR-240 — 50 Ohm, IP67, panel mount

The 031-6928: The IP67 rating means the mated pair seals against dust and water ingress — this is not a lab-only connector; it handles outdoor enclosures, washdown areas, and direct exposure. This material stack gives consistent 50 Ohm performance across temperature and frequency, with the gold centre contact good for the rated 500 mating cycles.

The bayonet lock gives quick mate/release; the IP67 seal is active when mated with a compatible BNC plug. Termination is crimp for the shield and solder for the centre contact — standard field practice for BNC on LMR-240. The shield termination is crimp; the centre contact is solder.

Frequently asked questions

Is 031-6928 compatible with LMR-240 cable?

Yes, the 031-6928 is specifically designed for LMR-240 coaxial cable. The cable group is listed as LMR-240, meaning the crimp ferrule and centre contact dimensions match that cable's dielectric and braid diameters.

Is the 031-6928 BNC jack 50 Ohm?

Yes, the impedance is rated at 50 Ohms, which is the standard for BNC connectors used in RF and video systems. The PTFE dielectric and gold-plated centre contact maintain that impedance up to 6 GHz.
