RS PRO Blue BNC Female to Female Test Box, 2 Connectors, Die Cast Aluminium Housing, 22.35mm x 57.15mm x 28.7mm 168-5185

RS PRO 168-5185 Blue BNC Female to Female Test Box features a robust die-cast aluminium housing with a blue painted finish and a clear anodised cover, designed for use in laboratory and diagnostic environments. This compact test box facilitates linking coaxial circuits via two BNC female connectors arranged for female-to-female coupling, ideal for portable RF signal routing tasks.

The gold-plated centre contacts minimize contact resistance, maintaining signal quality through the 50Ω nominal impedance design. The device has a maximum voltage rating of 335 VRMS, ensuring protection of inner conductor continuity during operation. Mechanical shielding is provided by the die-cast aluminium body, while steel screws secure the enclosure providing ruggedness for field use.

This test box operates reliably in a wide temperature range from −55°C up to +150°C, supporting usage in harsh and variable environments. It measures 22.35mm in height, 57.15mm in length, and 28.7mm in width, fitting conveniently on benchtops. The blue painted finish over a phosphoric etch and clear anodised aluminium cover provide corrosion resistance for longevity.

Applications include bench-top coaxial signal routing in test laboratories, quick link checks during RF diagnostics, portable coaxial testing, and field measurements with lab equipment requiring BNC interconnects. The test box is suitable for industrial, laboratory, manufacturing, and maintenance use cases where compact and reliable RF connectors are required.
