The silver-plated beryllium copper centre contact and brass body with nickel finish give it a corrosion-resistant signal path suited for repeated matings in test equipment, telecom racks, or instrumentation panels. The 500-cycle mating life means this jack holds up in field-service scenarios where the cable gets disconnected between shifts — the bayonet lock engages quickly and the silver plating on the mating surfaces keeps contact resistance stable through those cycles. ## Mounting Hardware and Panel Fit That means one line item covers the full bulkhead install — no separate hardware order for the sealing washer or lock ring. The gasket material is not specified in the listing, but the presence of a gasket in the kit tells you this jack is intended to seal against the panel face, not just clamp. Termination is solder cup on the centre conductor and solder shield termination — a straightforward field install with a standard iron. No crimp tool required, which keeps the install cost low for low-volume or prototype runs. The extended insulation feature (noted in the spec) gives extra creepage distance from the centre pin to the shell, relevant for the 500 V rating in humid environments.","metaTitle":"Amphenol RF 31-102 BNC Jack, 50 Ohm, 4 GHz, Panel Mount","metaDescription":"Amphenol RF 31-102 BNC jack, 50 Ohm, 4 GHz max, panel mount bulkhead.
