The gold-plated phosphor bronze centre contact is good for 500 mating cycles; that puts this jack in the field-serviceable range, not a one-crimp-and-forget part. The jack mounts through a bulkhead panel using the front-side nut and includes a lockwasher for vibration resistance. On the PCB side, the right-angle solder tails and the board lock anchor the connector against the torque of mating and unmating the bayonet plug. The dielectric is polypropylene (PP), which keeps the 50 Ohm impedance stable across the frequency range.","metaTitle":"Amphenol RF 031-5431-1010 BNC Jack, 1 GHz, 50 Ohm","metaDescription":"Amphenol RF 031-5431-1010 BNC jack, female socket, 50 Ohm, 1 GHz max, 500 V.
