Hammond 1590 Series Black Black Lid Die Cast Aluminium Enclosure, IP54 34 mm, 120 mm, 120 mm

When your electronic components need some shelter, pop them into this enclosure from Hammond. It has a low side wall angle of 2° or less, so you'll have no problem slotting in your PCB. Fixing the lid to the body is as easy as driving the included mounting screws through the factory-tapped holes and into the internal posts. As the screws are made from tough stainless steel, they stand up to corrosion in harsh settings. Lap-joint construction ensures the two parts of the box fit tightly, meaning signals from the board are protected against EMI.

• Polyester powder paint finish lets you stick on labels for easy identification

• Chemical plants

As it has an IP54 rating, this is a robust option that's protected against dust and water splashes from all directions, so it shrugs off contamination.
