The 1590BXFBK is a long, narrow diecast aluminum enclosure in a textured black finish with a flanged bottom plate, so the box can be fastened directly to a panel, wall or chassis. At a nominal 254 x 70 x 50 mm (10 x 2.76 x 1.95 in), it suits OEM engineers and integrators housing elongated circuit boards, sensor electronics or instrument assemblies that need a rugged metal case.

Box and lid are made from diecast aluminum alloy, which is tough yet easy to machine. The black version is coated with a tough polyester powder paint for a lasting finish even after machining, and black screws are included to match. A lap joint where lid and box meet protects against dust and splashing water, and the standard version is designed to meet IP54.
