Product details

50 Ohm BNC Bulkhead Kit — 4 GHz, 7-Piece Install Set

The 31-343-RFX: The 500-cycle mating life means this jack holds up on a test panel or a camera drop that gets reconnected regularly; the gold-plated phosphor bronze centre contact keeps the mating surface oxide-free across those cycles.

This kit is compatible with the RG-59, 62, 140, 210, and Belden 8241, 8263, 8279, 9209 cables. The crimp ferrule and centre contact are sized for the dielectric and braid diameters of those cables.

Bulkhead Install — Front-Side Nut, No Backside Access Needed

The mounting feature is bulkhead with a front-side nut — you drop the jack through the panel from the front and tighten the nut from the same side. That matters when the back of the panel is a rats-nest of cables or a sealed enclosure you don't want to open. The kit includes the gasket for a weather-resistant seal against the panel face; the lockwasher keeps the nut from backing off under vibration.
