The 1590BXBK is the black textured version of the 1590BX, the long and narrow member of the 1590 diecast aluminum family, with no mounting flanges. The part page lists 10 x 2.76 x 1.95 in (254 x 70 x 50 mm), a shape that suits OEM engineers and integrators housing elongated circuit boards within a compact cross-section.

The series ordering table and the drawing list 1590BXBK as the black version (the drawing calls it the Black Textured Enclosure), although the part page color attribute reads Natural Aluminum. Black 1590 enclosures are coated with a tough polyester powder paint for a lasting finish, even after machining, and come with black screws.

Outside, the drawing measures 254.00 x 70.00 x 49.50 mm [10.000 x 2.756 x 1.949 in]; inside there is 247.68 x 63.68 x 44.70 mm [9.751 x 2.507 x 1.760 in]. The side walls have a draft angle of 2 degrees or less for easy PC board mounting, and maximum P.C. board figures are 61.68 mm and 245.68 mm.

Six 6-32 UNC cover screws thread into factory-tapped holes at 50-55 cN.m [71-78 ozf.in]. The lap joint between lid and box protects against dust and splashing water, and this standard version is designed to meet IP54. The water-tight version is 1590WBXBK; the replacement gasket kit for this size is 1590BXGASKET.

Shipping weight is 0.9 lbs (0.41 kg), shrink wrapped. The 1590BXBK is RoHS and REACH compliant.
