RS PRO Blue BNC Female to Male Test Box, 2 Connectors, Die Cast Aluminium, 22.35mm x 28.7mm x 38.1mm 189-0258

RS PRO 189-0258 Blue BNC Female to Male Test Box is a specialized RF test enclosure designed to facilitate signal routing between coaxial connections in laboratory and field environments. This test box houses two BNC connectors arranged for female-to-male coupling within a sturdy die cast aluminium casing finished in blue enamel. With overall dimensions of 22.35mm height, 28.7mm width, and 38.1mm length, it is compact yet durable.

The test box supports 50 ohm nominal impedance systems, preserving RF performance essential for accurate testing. Its gold-plated beryllium copper centre contacts reduce contact resistance, ensuring superior conductivity and signal integrity. The enclosure withstands harsh environmental conditions, operating efficiently from -55ºC to +150ºC.

Electromagnetic interference is minimized through the die-cast aluminium housing with a plated body providing conductive shielding. The cover is attached securely using four self-tapping pan-head steel screws, and corrosion protection is provided by the blue baked enamel finish over a phosphoric etch, complemented by a clear anodised cover for surface protection.

This test box is ideal for portable RF troubleshooting, field tests, laboratory signal routing, short-term shielded interconnections, and maintenance checks under extreme temperature conditions. It facilitates quick connector conversion and works effectively with cable assemblies in diverse testing setups.
