Product details

The 031-70239: This is a male pin, right-angle crimp connector designed for free-hanging (in-line) cable termination. The 75 Ohm impedance targets digital video, broadcast, and broadband data applications — think SDI video routers, head-end equipment, and CCTV distribution where the transmission line is 75 Ohm coax.

This plug is specified for AT&T 734, AT&T 734A, and Belden 1505A cable — all 75 Ohm coax types with a nominal 0.180-inch diameter dielectric. The crimp termination uses a hex die for the shield ferrule and a separate crimp for the centre contact. Insertion loss is rated at 0.2 dB, and the frequency range extends to 4 GHz. The right-angle cable exit keeps the coax routed flat against the panel or chassis, useful in tight rack-mount enclosures.
