Fluke Test Box, 28.7mm Width, 38.1mm Length - 3752

This test box is a Compact RF test enclosure designed to facilitate signal routing between coaxial connections in laboratory and field environments. It houses a pair of BNC connectors configured for female-to-male coupling within a small, robust aluminium casing finished in blue enamel, and is intended for use with 50 ohm systems across a wide temperature range.

Features and Benefits:

• 500VRMS insulation limits voltage stress during testing
• Operates from -55ºC to +150ºC for harsh environments
• 50Ω nominal impedance preserves RF performance
• Two BNC connectors enable simple signal pass-through
• Gold-plated centre contacts reduce contact resistance

Applications

• Suitable for portable RF troubleshooting and field tests
• Used with cable assemblies for laboratory signal routing
• Ideal for quick connector conversion in test setups
• Can be used for short-term shielded interconnections
• Suitable for maintenance checks in temperature extremes

What material provides electromagnetic shielding?

The housing is die-cast aluminium with a plated body providing a conductive shield.

How are the connector contacts finished to ensure conductivity?

Centre contacts are gold-plated beryllium copper to maintain low resistance.

What fastening method secures the cover to the body?

The cover is attached using four self-tapping pan-head steel screws.

Is the finish corrosion-resistant and what type is used?

The exterior features a blue baked enamel over a phosphoric etch and the cover is clear anodised for surface protection.
