BNC Bulkhead Jack for RF Signal Paths
The 31-5431-2010: The connector uses a zinc die-cast body with nickel finish, a phosphor bronze centre contact plated in gold, and a polypropylene dielectric that holds its dielectric constant across the operating range. This is the isolated, board-guided variant in the 31-543 series, meaning the housing includes a board guide feature for alignment during PCB insertion and an isolated design that keeps the shell from grounding to the panel unless you want it to.
Mounting and Termination Layout
The right-angle solder tails exit the back for PCB mounting, which means the board runs parallel to the panel face. The kit ships with three pieces: the connector body, the lockwasher, and the nut — no separate hardware order needed for the panel install.
RF Performance and Signal Integrity
The 500-cycle mating life, backed by gold-on-phosphor-bronze centre contact, means the connector survives field reconnections without the centre pin wearing to a high-resistance state.
