Telegärtner BNC Straight Plug G1 (RG-58C/U) Pressure Sleeve J01000A0608

The Telegärtner BNC Straight Plug G1 (RG-58C/U) pressure sleeve stands out for its precision-machined brass body and gold-plated centre contact, ensuring reliable signal integrity up to 4 GHz. Unlike generic BNC connectors, this plug is engineered for crimp termination on RG-58C/U and compatible cables, providing a secure, low-loss connection in demanding RF applications.

Highlights

• 50 Ohm impedance for optimal signal transmission
• Gold-plated centre contact for corrosion resistance and consistent conductivity
• PTFE insulator for high-temperature stability and low dielectric loss
• Crimp termination for durable, vibration-resistant cable retention
• Wide operating temperature range from -40°C to +85°C

In daily use

This straight BNC plug is ideal for terminating RG-58C/U coaxial cable in video, RF, and test equipment. The pressure sleeve design provides strain relief, while the nickel-plated brass body offers mechanical robustness. With a VSWR of ≤1.3 at 3 GHz, it maintains excellent signal quality in high-frequency circuits.
