Mounts through a panel hole and secures with the front-side nut — you tighten from outside the enclosure, handy when the back side is inaccessible. Shield termination and center contact are both solder. Single port, panel mount with through-hole solder posts for the shield. The 031-70577-12G shares the same 75 Ohm, 12 GHz, bulkhead solder termination, and gold center contact — but its center contact material is listed as brass rather than phosphor bronze. The 031-70578-12G adds an isolated feature, which may matter if you need the connector body electrically isolated from the panel. The 031-70573-12G is a crimp termination version for cable (Belden 4505P), not solder. For a BOM that calls for a solder-bulkhead 75 Ohm BNC jack, the 031-70576-12G is the standard phosphor bronze contact variant.","metaTitle":"Amphenol 031-70576-12G BNC Jack, 75 Ohm, Bulkhead, 12 GHz","metaDescription":"75 Ohm BNC jack, bulkhead front-side nut mount, gold center contact, rated 12 GHz and 500 mating cycles.
