The crimp termination on both the shield and center contact means the cable braid is captured by the crimp ferrule and the center conductor is crimped into the gold-plated phosphor bronze contact — no solder, which speeds field termination and keeps the impedance consistent through the joint. The PTFE dielectric maintains the 75 Ohm line through the connector body. ## Cross-Shop: Panel-Mount vs In-Line The 031-70573-12G is a free-hanging in-line jack. If the build needs a bulkhead-mounted version, the 031-70576-12G and 031-70577-12G are both front-side nut panel-mount jacks with solder termination instead of crimp — same 75 Ohm, same 12 GHz, same 500-cycle rating, but the termination method and mounting flange change the assembly process. The 031-70572-12G is the mating plug (male pin) for this jack, also crimp-terminated for Belden 4505P, so a mated pair can be built with the same cable prep.","metaTitle":"Amphenol RF 031-70573-12G BNC Jack, 75 Ohm, 12 GHz, Crimp","metaDescription":"Amphenol RF 031-70573-12G BNC jack, 75 Ohm impedance, 12 GHz max frequency, crimp termination for Belden 4505P.
