Mini BNC Plug for 75 Ohm Coax — What's in the Kit
The Amphenol RF 031-70253 is a mini BNC plug, male pin configuration, built for 75 Ohm cable systems. The kit includes five pieces: the connector body, one contact, one ferrule, one insulator, and one sleeve, so you've got everything to terminate a cable end in one bag. The 75 Ohm impedance suits video, broadcast, or data-over-coax applications. The mini form factor saves panel space where a full-size BNC would crowd the backplane.
Cable Fit and Termination — What It Crosses To
This plug accepts RG-179, 179A, 179B, 187, 187A, Belden 9221, and M17/94-RG179 cables — all 75 Ohm miniature coax types with a similar dielectric diameter. The contact and shield are both crimp-terminated, so you need a crimp tool with the right die for the ferrule and centre pin. No soldering required on site, which speeds up field repairs. The nickel-plated brass body handles the shield termination and gives a clean appearance that doesn't tarnish quickly in a rack environment.
