The bayonet lock mates fast and holds under light vibration, which is why BNC is the go-to for test equipment, instrumentation front panels, and rack-mount RF distribution. The 500-cycle rating on the gold-plated phosphor bronze centre contact tells you this jack is meant for repeated connect-disconnect duty — think lab bench or field-service cable swaps, not a one-time permanent install.
Mounting and termination — board edge or panel wall
Shield termination is also solder, so the braid connection is made at the board, not through a separate ferrule.
