Product details

The 31-71008-1000: The 75 Ohm impedance marks it for video distribution, CCTV, and broadcast applications rather than the 50 Ohm RF bench standard — a critical distinction when matching system impedance.

Cable Compatibility and Termination — Sizing the Ferrule to the Jacket

This BNC plug is specified for RG-59, RG-59B, RG-62, RG-140, RG-210, and the Belden 8241, 8263, 8279, and 9209 cable types. The included crimp ferrule is sized for the outer jacket diameter of these cables — using a different cable group risks poor shield termination and degraded return loss. For a clean 75 Ohm termination, the cable prep must follow the manufacturer's strip lengths — the centre conductor exposure and braid trim directly affect the impedance through the connector interface. The 0.2 dB insertion loss figure assumes a proper termination on a listed cable type.

This means the manufacturer continues to support existing production but advises against specifying it for new projects. For existing BOM lines, the NRND status means lead time and availability should be confirmed at each procurement cycle.

The 2 GHz maximum frequency and 0.2 dB insertion loss define the signal path for composite video, SDI, and baseband data links up to that ceiling. The 500 V voltage rating covers the isolation requirement for equipment operating on mains-referenced supplies.
