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

This test box is a Compact RF enclosure designed to provide a simple Interface between BNC male and female connections for test and measurement tasks. It houses two BNC connectors in a small, painted die-cast aluminium cabinet with a removable cover, and is intended for use where a rugged, low-profile connection point is required in laboratory or field environments.

• Die-cast aluminium body provides Durable electromagnetic shielding
• Gold-plated centre contacts improve conductivity and corrosion resistance
• Operates to 1000VRMS between inner conductor and shield for high-voltage testing
• Rated for -55ºC to +150ºC to support varied temperature conditions
• Nominal 50Ω impedance ensures predictable RF performance
• Tarnish-resistant connector plating reduces maintenance needs

• Suitable for RF cable continuity and signal routing checks
• Used with BNC-equipped instruments for quick coupling
• Ideal for portable field measurement setups requiring rugged enclosure
• Can be used for laboratory bench interconnections during test routines
• Used for short-duration high-voltage verification of connector continuity

The male centre contact is gold-plated brass and the female centre contact is gold-plated beryllium copper.

The enclosure is finished with blue baked enamel over a phosphoric etch and the cover is clear anodised aluminium.

The shielded housing is a die-cast aluminium alloy and the cover is attached using four pan-head self-tapping screws.

Solder turret Terminal screws are steel to facilitate Durable soldered terminations.
