The 112440 is a BNC female to female bulkhead isolated adaptor designed for 75 ohm RF applications. It features a brass body with nickel plating, a phosphor bronze contact pin with gold plating, and a Delrin insulator for electrical isolation between the two BNC connectors. The adaptor operates across a frequency range of 0–1 GHz and supports a maximum panel thickness of 4.5 mm, with a recommended mounting hole diameter of 13.00 mm. This component is commonly used in RF test equipment, broadcast systems, and instrumentation where isolated connections between coaxial cables are required, providing reliable signal transmission while maintaining impedance matching.
