TNC Plug for LMR-240, 50 Ohm, IP67 — 031-6683-EE
50 Ohm Impedance and LMR-240 Cable Fit
The connector is specified for LMR-240 cable — a flexible, low-loss 50 Ohm coax with a 0.240-inch diameter. The crimp termination for both center contact and shield produces a consistent, repeatable termination that maintains the 50 Ohm characteristic through the connector-to-cable transition. For a bulkhead-mounted TNC jack on the same cable group, the sibling 031-6962 uses a solder center contact instead of crimp, which changes the termination tooling required.
IP67 Sealing and 500-Cycle Durability
The IP67 rating means the mated connector pair withstands temporary immersion in 1 meter of water — suited for outdoor antenna mounts, marine electronics, or industrial washdown zones. The threaded fastening maintains compression on the O-ring seal better than a bayonet lock under vibration. With 500 mating cycles, this plug supports periodic disconnect for equipment servicing without wearing out the gold-on-beryllium-copper center contact.
