The 1590KBK is the black textured version of the 125 mm square, 79 mm tall enclosure in the 1590 Series. At 4.92 in x 4.92 in x 3.11 in (125 mm x 125 mm x 79 mm) it gives designers of instruments, controllers and custom electronics a deep, rugged metal housing with a finished look straight out of the box.

The box and lid are diecast aluminum alloy, coated with a tough polyester powder paint that gives a lasting finish even after machining, so holes and cut-outs can be added without losing the black appearance. Black screws are included to match. A lap joint between lid and box protects against dust and splashing water, and the enclosure is designed to meet IP54.

Inside dimensions from the drawing are 118.10 mm [4.650 in] in length and width and 73.50 mm [2.894 in] in height, with a listed maximum P.C. board size of 116.1 mm square. Side walls use a draft angle of 2° or less to simplify board mounting. This version has no mounting flanges; the 1590KFBK adds a welded flanged bottom plate.

Each assembly includes the box, lid and 4 cover screws in factory-tapped 6-32 UNC holes, with a recommended torque of 50-55 cN.m [71-78 ozf.in]. For IP65, fit the 1590KGASKET kit with watertight stainless screws and torque to 25-30 cN.m [36-43 ozf.in], or choose the ready-made 1590WKBK. The 1590KBK is RoHS and REACH compliant and ships shrink wrapped at 0.97 lbs (0.44 kg).
