The silver-plated beryllium copper centre contact gives good conductivity and spring retention across repeated mates. The 500 mating cycles mean this jack holds up well in field-service or test-bench environments where cables get swapped regularly. The cable group list — RG-174, 188, 188A, 316, LMR-100, M17/119-RG174 — covers the thin, flexible coax types that fit the standard BNC crimp ferrule. If you're terminating a different cable diameter, check the outer jacket OD against the clamp range; the shield termination is a clamp style, so the braid gets captured mechanically before the centre conductor is crimped or soldered. ## What Comes in the Box and How It Goes Together The centre contact can be crimped or soldered — the choice depends on your tooling and whether you need a field-repairable joint. The braid clamp and gasket handle the weather seal and strain relief when assembled correctly.","metaTitle":"Amphenol 031-5 BNC Jack, 50 Ohm, 4 GHz, 500 V, Weatherproof","metaDescription":"Amphenol 031-5 BNC jack, 50 Ohm, 4 GHz max, 500 V rated, weatherproof, bayonet lock.
