DESCRIPTION

The 031-4890-1 is a BNC 50 ohm bulkhead receptacle designed for front mount applications with isolation from the panel using metal mounting threads. It features a solder cup terminal type and is constructed with a D1 insulation material, providing reliable RF connectivity in demanding environments. The connector has a length of 1.06 inches (27.0 mm), a body diameter of 0.625 inches (15.9 mm), and a contact diameter of 0.571 inches (14.5 mm), with a mounting hole depth of 0.187 inches (4.7 mm). This isolated panel-mount configuration is ideal for applications requiring RF signal transmission with electrical isolation from the mounting surface, such as test equipment, communications systems, and instrumentation where clean RF performance and mechanical stability are essential.
