Product details

BNC Jack, Isolated, 50 Ohm — Panel Mount with Right-Angle PCB Tails

The 031-5540: The isolated body (DC-blocked from the shell) prevents ground loops in sensitive RF instrumentation or test setups where the shield path needs to float.

Mounting and Termination — Bulkhead Front Nut with Right-Angle Solder Tails

The contact termination is solder, with the centre pin and shield tails bent at a right angle for PCB mounting.
