Telegärtner BNC Bulkhead Jack, Isolated 75 Ohm, White Insulating Washers, 1 Piece (J01003B1286)

For RF technicians and broadcast engineers terminating 75-ohm coaxial lines at patch panels or equipment enclosures, this Telegärtner BNC bulkhead jack provides a ground-isolated connection point. The white insulating washers separate the connector body from the panel, preventing ground loops in sensitive video or data circuits.

Why choose it

The isolated design prevents ground loops, and the PTFE dielectric ensures low loss up to 1 GHz. Gold-plated contacts maintain signal integrity over repeated mating cycles.

Ideal use cases

• Broadcast video patch panels
• Telecom equipment interfaces
• Test and measurement setups

Good to know

This connector is sold individually. It requires soldering of the center conductor for termination.
