The 132191 is an SMA bulkhead crimp jack connector manufactured by Amphenol RF for use with RG-55, RG-142, RG-223, and RG-400/U coaxial cables. This connector features a brass body with gold finish, a beryllium copper contact pin, and a teflon insulator, providing reliable RF signal transmission and mechanical durability. The connector utilizes a 1/4–36UNS–2A threaded interface with an 8-hex nut design for secure panel mounting, and includes a ferrule, lock washer, and hex nut assembly for robust installation. The recommended mounting hole diameter is 12.70 mm (0.500 inches), with cable stripping dimensions of 6.50 mm (0.256 inches) outer and 6.00 mm (0.237 inches) inner. This bulkhead configuration is ideal for applications requiring permanent panel-mounted RF connections in telecommunications, test equipment, and microwave systems where reliable impedance matching and signal integrity are essential.
