Product details

What This BNC Plug Carries and Where It Fits

The 31-4541-RFX: The clamp-style shield termination and solder contact termination suit field assembly: you strip the coax, solder the centre pin, then clamp the braid under the nickel-plated brass body. The listed cable group covers RG-59, RG-62, RG-140, RG-210, and Belden 8241, 8263, 8279, 9209 — the clamp accommodates the dielectric diameters of these cables without a special adapter. Insertion loss is spec'd at 0.2 dB — low enough that the connector doesn't eat into your link budget in a short cable run.

Cable Fit and Assembly Check

Before ordering, confirm your coax is in the supported cable group: RG-59, 59B, 62, 140, 210, Belden 8241, 8263, 8279, 9209. The clamp and centre contact are sized for these cable diameters — a different coax may not seat properly under the clamp or may shift the impedance away from 50 Ohm.
