Mini Dustproof Junction Box

This pack contains four black ABS enclosures designed to shield small electronic assemblies from dust in indoor environments. Each box measures 80 by 50 by 26 millimetres externally and offers an internal cavity of 75 by 46 by 20 millimetres. The material provides electrical insulation and flame-retardant properties for general-purpose protection. Supplied without pre-drilled openings, they require the user to create cable entries as needed.

DIY builders needing compact indoor housings

Hobbyists and technicians assembling power modules, USB boards, switches or terminal blocks will find the internal volume adequate for such components. The snap-on lid allows quick access during prototyping or maintenance tasks. Installations that demand a sealed, waterproof rating or outdoor exposure should look elsewhere, as the boxes are rated only for dust protection. Projects requiring pre-punched knockouts or integrated gland fittings are also not suited to this design.

Snap-on lid with user-drilled entries

The closure mechanism relies on a simple snap fit that secures the cover once internal parts are positioned. Because no wiring holes are moulded into the enclosure, every cable or conduit entry must be drilled by the installer to match the specific layout. This single characteristic determines whether the box fits a project that can accommodate custom drilling versus one that needs ready-made ports.

Questions about this item

What internal dimensions does the 80x50x26mm enclosure provide for a power module?

The internal cavity measures 75x46x20mm, leaving enough room for small power and USB modules, switches or terminal blocks.

Which installation step is most often missed when sealing the ABS box?

Drilling the required wiring holes before snapping the cover shut is the step users forget; the box ships with no pre-cut openings.

How often should the ABS enclosure be inspected for dust ingress in indoor use?

Check the snap-fit seal annually; the dustproof design relies on the cover staying fully latched, and the ABS material itself needs no scheduled replacement.
