Shielded Aluminium Box 3230

The Pomona Electronics 3230 is a shielded aluminium enclosure designed to protect sensitive signal connections. Its blue enamel finish resists corrosion while the integrated BNC female connectors provide ready-to-use RF access points for test and measurement setups.

Upgrade From Unshielded Enclosures

This box replaces basic plastic or unshielded metal housings when electromagnetic interference degrades signal integrity. The jump is worth it whenever coaxial cables enter a panel and the circuit demands a continuous ground path through the enclosure walls.

Compact Internal Volume

The 1.38 in height, 2.25 in width and 1.13 in depth create a small cavity that comfortably holds a few BNC bulkhead adapters and short cable tails. It runs out of space quickly when additional terminal blocks or larger connectors are required.

Questions about this item

What are the exact dimensions of the 3230 shielded box so I can check if it fits my panel cut-out?

The enclosure measures 2.25 in wide, 1.38 in high and 1.13 in deep, giving you the precise footprint needed for panel planning.

How do the included #2-32 self-tapping screws fasten the cover, and what is the common mistake?

The four steel pan-head screws thread directly into the aluminium box; the frequent error is over-torquing and stripping the soft threads.

Will the enamel finish or the BNC connectors need periodic replacement in a marine environment?

The blue enamel coating resists corrosion, and the panel-mount BNC females are rated for long service; neither item has a scheduled replacement interval.
