The zinc die-cast body with nickel finish provides RF shielding and environmental protection in indoor equipment racks or lab setups. ## Mounting and Termination — Bulkhead Feedthrough with Solder Shield The shield termination is solder — you solder the braid or ground plane directly to the body for a low-impedance RF return path. The center contact terminates via a solder cup, making it straightforward to attach a coaxial cable center conductor. The right-angle body keeps the cable low-profile against the board, useful in tight enclosures. ## Board Guide and Isolation Features The 31-5431 includes a board guide and is listed as isolated. The isolation feature means the body is electrically isolated from the mounting panel — useful when you need to break ground loops or avoid a chassis ground connection at the bulkhead.","metaTitle":"Amphenol RF 31-5431 BNC Jack, 50 Ohm, 1 GHz, Right Angle","metaDescription":"Amphenol RF 31-5431 BNC jack, 50 Ohm, 1 GHz, 500 V, right-angle PCB mount with bayonet lock.
