Product details

75 Ohm BNC Plug Kit for AT&T 735A Cable Runs

The Amphenol 031-70240 is a BNC plug kit — a 75 Ohm variant, not the standard 50 Ohm BNC found in most test equipment. That 75 Ohm impedance matches it to video, broadcast, and telecom cable systems like AT&T 735, 735A, and Belden 735A1. Bayonet lock secures the mate — a quarter-turn and it's locked, no tool needed.

The cable group compatibility is specific: AT&T 735, 735A, and Belden 735A1. Those are 75 Ohm coax cables with a nominal impedance that matches the connector. Using a different cable changes the impedance at the crimp point and degrades the return loss.

Durability and Termination

The brass body with nickel finish gives a corrosion-resistant shell that grounds through the bayonet lock.
