Product details

The Amphenol RF 31-5136-RFX is a BNC plug from the Suretwist® series, terminated with a push-on contact and a twist-on shield — the field-installable method that skips soldering the braid.

Cable Fit and Frequency Ceiling

This plug is listed for RG-59, RG-62, RG-140, RG-210, and Belden 8241, 8263, 8279, 9209. Insertion loss is 0.2 dB.

Construction and Plating

Brass body with nickel finish, brass center contact with gold plating, and a polyoxymethylene (POM) acetal dielectric. The gold-on-brass center contact handles the 500 V rating without corrosion creep in a humid or outdoor patch-panel environment. The twist-on shield termination bonds the cable braid to the shell in one motion — no ferrule to crimp, no solder pot to fill.
