This is the impedance standard for video, broadcast, and telecom signal paths — a 50 Ohm connector would introduce a reflection at the junction. Rated to 2 GHz with an insertion loss of 0.15 dB, this plug covers SDI video, baseband analog, and RF distribution within that band. The 500 mating cycles, supported by the gold-plated brass center contact, suit it for test equipment or any interconnect that sees regular reconnection. The specified cable group covers Belden 1164A and 1167A, both common 75 Ohm coax types for video and data.
This plug is listed for Belden 1164A and 1167A cables. Both are 75 Ohm, dual-shielded coax with a solid or stranded center conductor in the 20-22 AWG range. The crimp ferrule and center pin are sized to match the cable's dielectric diameter and braid coverage — using a different cable risks an impedance step or a loose crimp that pulls out under tension. The polyethylene dielectric material in the connector body matches the dielectric constant of the cable's foam PE, keeping the 75 Ohm characteristic impedance continuous through the junction.
