The Molex 0731000167 is a BNC jack from the 73100 series — a 50 Ohm, single-port, female socket connector built for coaxial signal paths where the bayonet lock gives a quick quarter-turn mate. The 50 Ohm impedance sets the characteristic line impedance for RF and video signal runs; the connector maintains that impedance through the bulkhead transition. Gold-plated centre contact on phosphor bronze, nickel-plated zinc alloy body. Rated for 500 mating cycles, which covers field-service reconnections and test-point duty without contact wear becoming the failure mode.
Mounting and termination — three ways to land it
Panel mount, through hole, and right-angle solder legs — the 0731000167 carries all three mounting options in one body. Shield termination is solder, not a crimp ferrule — expect to hand-solder the braid to the shell.
Dielectric and isolation
Polypropylene (PP) dielectric between centre and outer conductor. The isolated body feature means the shell is not tied to the signal ground internally — useful in installations where you need to break a ground loop between the panel and the coax shield.
