The 112420 is a BNC bulkhead receptacle plug from Amphenol Connex, engineered for panel-mounted coaxial connections. It features a durable nickel-plated brass body, a gold-plated brass contact pin for superior conductivity, and an insulator made from PTFE and Delrin. Designed for a recommended mounting hole of 9.70 mm, it is secured using a 3/8-32UNEF-2A threaded hex nut. This connector is ideal for applications requiring a robust, chassis-grounded BNC interface, such as in test equipment, communication panels, and instrumentation.
