Product details

TNC Right-Angle Plug for 11 GHz RF Links

The 031-6003-RFX: The threaded coupling ensures a vibration-resistant mate, and the 500 mating cycles support field-service reconnections without degrading the gold-plated centre contact. This connector is built for Belden 9258 and LMR-240 cable groups, with a brass body finished in nickel and a polyoxymethylene (POM) acetal dielectric.

How It Compares to 031-2367-RFX

The 031-2367-RFX is a close functional peer: same TNC plug style, same 50 Ohm impedance, 11 GHz max frequency, and 500 mating cycles. The key difference is cable group — 031-2367-RFX targets RG-55, 142 A, and 400, while 031-6003-RFX is for Belden 9258 and LMR-240. Also, 031-2367-RFX uses a crimp contact termination, whereas 031-6003-RFX uses solder for the centre pin. Choose based on your cable type and termination preference.
