Telegärtner BNC Bulkhead Jack, Isolated 50 Ohm, Black Insulating Flange, Gold-Plated Contacts, 4 GHz, 1 pc

This BNC bulkhead jack stands out with its isolated panel mounting and black insulating flange, providing electrical separation from the chassis while maintaining a secure 50-ohm connection. The gold-plated center contact and nickel-plated brass body ensure reliable signal integrity up to 4 GHz.

Highlights

• Isolated bulkhead design with black insulating flange
• 50 Ohm impedance for RF applications
• Gold-plated center contact for low resistance
• Wide frequency range DC to 4 GHz
• PTFE insulator for high-temperature performance

In daily use

Ideal for panel-mounted coaxial connections in test equipment, communications systems, and industrial electronics. The isolation flange prevents ground loops and allows floating shield configurations. With a mounting hole diameter of 12.7 mm and maximum panel thickness of 3.2 mm, it fits standard bulkhead cutouts. The connector withstands over 500 mating cycles, ensuring long service life.
