TELEGÄRTNER BNC Bulkhead Adapter Jack to Jack 50 Ohm J01004A1231

This BNC bulkhead adapter from TELEGÄRTNER delivers a 50 Ohm impedance with a VSWR of ≤1.25 at 1 GHz, ensuring reliable signal integrity up to 4 GHz.

Overview

The J01004A1231 is a panel-mount BNC coupler featuring a jack-to-jack (female-to-female) configuration. It is designed for through-panel connections where a secure, low-loss link is required. The adapter body is made of nickel-plated brass, while the contacts are gold-plated for excellent conductivity and corrosion resistance. PTFE insulation provides stable dielectric performance across the operating temperature range of -40 °C to +85 °C.
