The kit ships as 9 pieces — the connector body, braid clamp, clamp, centre contact, two gaskets, lockwasher, nut, and washer — so the buyer gets everything needed for a single cable termination in one order code. ## Cable Compatibility and Electrical Performance This jack is designed specifically for RG-402 (.141\" semi-rigid) cable. The 500 V voltage rating and silver-plated centre contact (beryllium copper) suit it for moderate-power RF paths where signal integrity matters more than raw current. The brass body with silver finish and PTFE dielectric keeps the signal path stable across temperature swings.","metaTitle":"Amphenol RF 031-4220 BNC Jack, RG-402, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF 031-4220 BNC jack, 50 Ohm, 4 GHz max, for RG-402 semi-rigid cable.
