The IP67 rating (dust-tight and waterproof when mated) makes this suitable for outdoor antenna feeds, marine electronics, or industrial RF links where moisture ingress would degrade the signal path. ## RG-58 Cable Fit — What the Crimp and Solder Mean for Field Assembly This plug is spec'd for the RG-58 cable group. The crimp shield termination requires the correct hex die for RG-58 braid diameter — using the wrong die can deform the ferrule and change the impedance at the termination point. The solder contact means the center pin is hand-soldered to the signal conductor; a cold joint or excess solder wicking up the dielectric will shift the 50 Ohm line. For field-service techs, the threaded fastening provides a vibration-resistant mate that the bayonet-lock BNC cannot match in high-shock environments. No obsolescence notice or last-time-buy date is on record. The base product number is 031-69; the 031-6923 is the RG-58 male plug variant within that family. ## Cross-Shop: 031-6921 vs 031-6923 The 031-6921 is the bulkhead-mount jack (female socket) counterpart in the same TNC series. Both share the 50 Ohm impedance, 6 GHz frequency rating, IP67 sealing, and 500 mating cycles. The 031-6921 mounts through a panel with a front-side nut and is spec'd for LMR-240 cable group, not RG-58. If the BOM calls for a panel-feedthrough TNC on LMR-240, the 031-6921 is the correct jack; the 031-6923 is the free-hanging plug for the RG-58 cable assembly that mates to it.","metaTitle":"031-6923 TNC Plug, Male Pin, 50 Ohm, 6 GHz, IP67, RG-58","metaDescription":"031-6923 TNC plug, male pin, 50 Ohm impedance, 6 GHz max frequency, IP67 sealed, crimp/solder termination for RG-58 cable.
