The 1590LBK is the satin black painted version of the slim 1590L diecast aluminum enclosure. It suits designers of pedals, test gear and compact OEM electronics who want a finished black exterior on a small, narrow box with internal ribs for guiding a P.C. board.
The body and lid are diecast aluminum alloy, tough yet easy to machine, and painted with tough polyester powder paint for a lasting finish even after machining. Black screws are included to enhance appearance. The lid attaches with 4X M3.5x0.6 x 12.00 mm screws that thread into factory-tapped holes, and lap joint construction helps keep out dust and splashing water for an IP54 rating.
Listed size is 3.96 in x 1.97 in x 0.98 in (101 mm x 50 mm x 25 mm) with a shipping weight of 0.22 lbs (0.10 kg). Inside, the drawing shows 97.29 mm [3.830"] of length, 43.22 mm [1.702"] of width and 21.05 mm [.829"] of height. Maximum P.C. board size is 93.71 mm by 42.61 mm, and the side walls have a draft angle of 2 degrees or less to make board mounting easier.
The 1590LBK is RoHS and REACH compliant and ships shrink wrapped. Black replacement screws (1550MS100BK) and black Torx tamper-resistant screws (1550MS50TBK) are offered for this size.
