RS PRO, Blue BNC Female to Female Test Box, 2 Connectors

This test box is a Compact enclosure designed for linking coaxial circuits via two BNC female receptacles and is intended for laboratory and diagnostic use where portable RF connections are required. The housing is formed from die-cast aluminium with a blue painted finish and a separate clear‑anodised cover, and it is suitable for handling RF signal routing tasks within its operating temperature range.

• 335VRMS maximum voltage rating protects inner conductor continuity
• 50Ω nominal impedance preserves signal integrity
• Die-cast aluminium housing provides mechanical shielding
• Gold-plated centre contacts reduce contact resistance
• Wide operating temperature range supports harsh environments

• Suitable for bench-top coaxial signal routing in test labs
• Used for quick link checks during RF diagnostics
• Ideal for portable coaxial testing and field measurements
• Can be used with lab equipment requiring BNC interconnects

The centre contacts are gold-plated, with male contacts in brass and female contacts in beryllium copper.

The shielded housing uses a blue paint over a phosphoric etch and the cover is clear‑anodised aluminium.

The unit uses steel screws including self-tapping pan-head screws and #4-40 Terminal screws for internal connections.

The device is rated to operate from −55°C up to +150°C.

There are two BNC female connectors arranged for female-to-female coupling.
