Product details

The connector is built for RG-402 (.141" semi-rigid) cable, with a gold-plated stainless steel body and a PTFE dielectric. The center contact is beryllium copper with gold plating, and the shield terminates via solder. Threaded fastening and a flange mounting feature provide a vibration-resistant, grounded panel installation.

The gold-on-beryllium copper center contact maintains consistent force and low resistance over that life. The 500 V voltage rating covers most signal-level and low-power RF applications.
