Product details

75 Ohm Mini BNC Plug for RG-Type Cables

The Amphenol 031-70340 is a mini BNC plug with a 75 Ohm impedance, designed for video, broadband, and data applications up to 1 GHz. It is the male pin (plug) half of the mini-BNC interface, mating with a standard mini-BNC jack. The 75 Ohm impedance matches video distribution and broadcast equipment where 75 Ohm coax is standard. The 1 GHz frequency ceiling covers analog video and most digital video signals up to HD-SDI.

This plug accepts RG-122, RG-180A, RG-180B, RG-195, Belden 1855, and Belden 1865A cables. The phosphor bronze body with nickel finish provides corrosion resistance in indoor equipment racks.

RF Performance and Construction

Insertion loss is specified at 0.1 dB, and the PTFE dielectric maintains consistent impedance through the signal path. The bayonet lock gives a positive quarter-turn mate with audible feedback — no threads to cross, no torque specification to meet.
