Product details

The 031-70000: The 75 Ohm impedance targets video distribution, broadcast, and broadband data applications where 50 Ohm BNCs would introduce a mismatch.

Cable Fit and Termination — What It Accepts

The cable group listed covers RG-6 and RG-6A (common for CATV/SAT), RG-54, RG-143, RG-212, and several Belden equivalents. If you're terminating RG-59, this plug is not the match — the dielectric diameter and braid lay differ; look at the 034-1026 for that cable group. That wide range suits outdoor enclosures and unheated cabinets where standard PVC-dielectric connectors soften or crack.

The 031-70016 is the bulkhead-mount jack counterpart — female socket, front-side nut mounting, same 75 Ohm impedance and 4 GHz bandwidth. Where this plug terminates a cable end, the 031-70016 mounts through a panel and accepts the plug. Both share the 500-cycle bayonet lock and 0.2 dB insertion loss. Choose the plug for the free-hanging cable end; choose the jack for a fixed panel point.

Frequently asked questions

Which cable types are compatible with 031-70000?

RG-6, RG-6A, RG-54, RG-143, RG-212, plus Belden 1152A, 89248, and 9290. RG-59 is not in the listed group; for RG-59 use the Amphenol 034-1026.
