The 1590BBK is a textured black diecast aluminum enclosure from the 1590 Series with no mounting flanges, measuring a nominal 4.43 in x 2.38 in x 1.22 in (113 mm x 60 mm x 31 mm). It suits OEM engineers, hobbyists and integrators building instruments, controls and small electronic assemblies that sit on a bench, shelf or panel without external mounting ears. Note that 1590BBK belongs to the 1590B size (4.41 in x 2.40 in x 1.22 in in the ordering table), which should not be confused with the 1590BB size.
Box and lid are diecast aluminum alloy, which is tough yet easy to machine for connectors, switches and displays. It is coated with a tough textured polyester powder paint that keeps a lasting finish even after machining, and black screws are included to match. Lap joint construction where the lid meets the box helps keep out dust and splashing water, and this standard version is designed to meet IP54. Side walls have a low draft angle of 2° or less, which makes mounting a PC board easier.
Per the drawing the box measures 112.40 mm [4.425 in] long by 60.50 mm [2.382 in] wide, with an overall height of 31.00 mm [1.220 in]. Inside you get 107.05 mm [4.215 in] of length, 55.45 mm [2.183 in] of width and 27.00 mm [1.063 in] of height, and the maximum P.C. board size is listed as 53.45 mm by 105.05 mm. The lid height is 0.16 in (4 mm).
The assembly ships with the box, lid and 4 cover screws that thread into factory-tapped 6-32 UNC holes; the recommended torque is 50-55 cN.m [71-78 ozf.in]. To upgrade to IP65, add the 1590BGASKET silicone gasket kit, torque the lid screws to 25-30 cN.m [36-43 ozf.in], and consider the stainless steel O-ring cover screws (1590WMS100BK). Shipping weight is 0.44 lbs (0.20 kg).
