Telegärtner BNC Female Crimp Connector 50 Ohm for RG58 C/U, UG-1794/U, Nickel/Gold, 1 pc J01001A1265Z

The Telegärtner J01001A1265Z stands out as a precision BNC female connector engineered for reliable 50-ohm RF connections in professional and industrial environments. Its crimp/crimp termination ensures a secure, tooled attachment to RG58 C/U coaxial cable, delivering consistent impedance and low signal loss across DC to 4 GHz. The nickel-plated brass body offers corrosion resistance and mechanical durability, while the gold-plated center contact maintains excellent conductivity and long-term performance. Designed to the UG-1794/U standard, this connector is a direct replacement for many RF applications requiring a robust, high-frequency interface.

Highlights

• BNC female (jack) connector with 50 Ohm impedance
• Crimp termination for RG58 C/U coaxial cable
• Nickel-plated brass body, gold-plated brass contact
• PTFE insulator for stable dielectric properties
• Frequency range DC to 4 GHz, VSWR ≤ 1.3:1 at 3 GHz
• Operating temperature -40 °C to +85 °C
• Conforms to UG-1794/U standard

In daily use

Installers and technicians will appreciate the straightforward crimp assembly, which provides a gas-tight connection that resists pull-out and maintains shielding integrity. The connector's compact size and standard BNC interface allow quick mating and unmating without tools, making it suitable for test setups, antenna feeds, and video transmission systems. The PTFE insulation ensures stable impedance over temperature extremes, while the nickel plating protects against environmental wear.
