75 Ohm HD BNC Plug for Belden 1695A — What This Connector Is
The Amphenol 034-1027 is a 75 Ohm HD BNC plug, built for precision video and telecom signal paths where the 75 Ohm impedance match matters more than the generic 50 Ohm BNC standard. This is the high-density variant — the HD in the connector style means a slightly smaller shell profile than a standard BNC, designed for higher packing density on patch panels and equipment faces. The cable group is specced for Belden 1695A, a precision 75 Ohm coaxial cable common in broadcast video and high-end CCTV runs. The crimp termination — both shield and centre contact — gives a repeatable, tool-controlled termination that keeps the impedance consistent through the joint.
4 GHz Bandwidth and the 75 Ohm Signal Path
Rated to 4 GHz, this HD BNC covers the full baseband video spectrum (up to 3 GHz for 12G-SDI) with headroom.
