The 112575 is a BNC bulkhead receptacle jack connector manufactured by Amphenol RF, designed for RF signal transmission in panel-mount applications. It features a 50-ohm impedance with a dielectric withstanding voltage of 1000 VRMS minimum, ensuring reliable high-frequency performance. The connector is constructed with a zinc diecast body with nickel plating, phosphor bronze contacts with gold plating, and a Delrin insulator, providing durability and corrosion resistance. It supports a maximum panel thickness of 3.3 mm and operates reliably across a temperature range of -40°C to +85°C with a mechanical durability rating of 500 cycles minimum. This connector is commonly used in RF equipment, test instrumentation, and communication systems where secure panel-mount connections and impedance matching are critical.
