Product details

Panel-Mount TNC Jack for LMR-240, Sealed to IP67

It is terminated to LMR-240 cable — the crimp shield and solder center contact are sized for that specific cable group's dielectric diameter and braid coverage. The 50 Ohm impedance holds through 6 GHz, with a PTFE dielectric keeping the phase stable across the band. Gold plating on the beryllium copper center contact resists corrosion over 500 mating cycles; the threaded coupling nut delivers a vibration-resistant mate that holds torque in outdoor enclosures.

Sealing and Environment

Rated IP67, this jack seals dust-tight and survives immersion when mated with the corresponding TNC plug.

Designed specifically for LMR-240 cable. The crimp ferrule compresses over the jacket and braid; the center contact solders to the center conductor.

Frequently asked questions

Is the 031-6921 compatible with LMR-240 cable?

Yes, the 031-6921 is specifically designed for LMR-240 cable group, with the crimp ferrule and center contact sized for that cable's dielectric and braid.
