Product details

What This BNC Plug Kit Covers

The Amphenol RF 31-4700 is a BNC plug kit — a male pin connector for 50 Ohm coaxial cable assemblies. It comes as three pieces: the connector body, one center contact, and one ferrule, so you're not sourcing those separately. The 500 mating cycles rating means it's built for test-bench reconnect duty, not just a one-time permanent install.

This plug is designed for a specific group of 50 Ohm coaxial cables: RG-58, 58A, 58B, 58C, 141, 303, LMR-195, Belden B7806A, and 9907. Yes, LMR-195 is on that list — the crimp ferrule and center contact dimensions match the jacket and dielectric diameters of LMR-195. The contact termination can be crimp or solder; the shield is crimped. For a field-terminated RG-58 run, this kit saves tracking down a separate ferrule.
