75 Ohm BNC Mini Plug for Video/Telecom Cable Runs
The Amphenol 031-70333 is a 75 Ohm BNC mini plug — the right-angle, solder-contact, crimp-shield termination variant in the mini BNC family. It is designed for video, CCTV, and telecom signal paths where the 75 Ohm impedance matches standard coaxial cable runs like AT&T 735, 735A, or Belden 735A1. The 1 GHz maximum frequency and 0.1 dB insertion loss keep the signal clean through the interconnect, making it a fit for baseband video distribution and low-frequency data links where a full-size BNC is overkill.
500 Mating Cycles and Bayonet Lock for Field Service
The bayonet lock provides a positive, vibration-resistant mate that a field tech can engage without tools — the right-angle body keeps the cable routed close to the panel face. The PTFE dielectric handles the -40°C to 155°C operating range, so it lives in outdoor telecom cabinets or industrial enclosures without issue.
Kit Contents: Connector, End Cap, Ferrule
The 031-70333 ships as a 3-piece assembly: the plug body with pre-installed centre contact, a separate end cap, and a crimp ferrule. The end cap threads onto the plug after the cable braid is folded back; the ferrule crimps over the braid to terminate the shield. This kit format means the harness builder gets everything needed for one cable end in one package — no separate ferrule or cap to source.
