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

This test box is a Compact enclosure designed to connect two BNC female Interfaces for signal routing and evaluation in laboratory and field settings. The housing is formed from die-cast aluminium with a blue finish and a clear anodised cover, providing a protected Interface for RF and general-purpose testing. It operates across a wide temperature range and is intended for use where a small, portable BNC coupling solution is required.

• 50 Ohm nominal impedance ensures consistent RF matching
• 500 VRMS maximum between inner conductor and shield for safety
• -55°C to +150°C operating range for harsh environments
• Gold-plated beryllium copper contacts for low-resistance connections
• Die-cast aluminium body for mechanical robustness

• Used with bench RF test equipment requiring inline coupling
• Suitable for portable field measurement set-ups needing quick adapters
• Ideal for temporary signal routing in laboratory experiments
• Can be used for continuity checks between BNC-equipped devices

The connectors use gold-plated beryllium copper for the contact elements to maintain low contact resistance and corrosion resistance.

The housing receives a blue paint over a phosphoric etch, while the cover is clear anodised aluminium for added surface protection.

Four steel pan-head self-tapping screws fasten the cover to the housing.

The inner conductor-to-shield rating is 500 VRMS maximum under normal conditions.

The shielded housing is a die-cast aluminium alloy A380 or A384 to provide structural integrity.
