The 1590WBSBK is the black textured, water-tight 1590BS diecast aluminum enclosure, a deeper box on the 1590B footprint with no mounting flanges. It suits OEM engineers, instrument builders and integrators looking for a compact painted metal housing with extra depth, designed to meet IP65.

Construction is diecast aluminum alloy for box and lid. The black version is coated with tough polyester powder paint for a lasting finish, even after machining, and black screws are included to enhance appearance. A lap joint where lid and box meet protects against dust and splashing water. The silicone gasket is included and supplied loose, so the enclosure can be machined and/or painted first and gasketed later.
