Hammond 1591DTCL 150x80x50 mm Crystal Clear Polycarbonate PCB Enclosure

The 1591DTCL is a Crystal Clear polycarbonate enclosure in a larger 150 x 80 x 50 mm case. It is a transparent housing for larger printed circuit boards and assemblies where the internal parts, sensors or indicators need to be seen.

The Crystal Clear version is almost totally transparent, letting you see parts, sensors or indicators inside without opening the lid. The case is molded from flame retardant translucent polycarbonate that is easy to machine, and lap joint construction between box and lid provides protection against access of dust and splashing water. It is designed to meet IP54 and is listed as RoHS and REACH compliant.

The drawing gives overall dimensions of 150.00 x 80.00 x 50.00 mm (5.906 x 3.150 x 1.969 in). With 143.62 x 73.62 x 45.60 mm inside, it accommodates longer boards and more component height than the smaller sizes in the series. Integral card guides accept 1.5 mm (0.062 in) PC cards, with a guide height of 40.60 mm and a slot width of 2.11 mm.

The purchased 1591DTCL assembly includes the box, lid, 4 cover screws and pre-installed brass inserts. The lid is secured with M3 x 10 mm Phillips machine screws threaded into integral brass bushings at a recommended torque of 42-57 ozf.in (30-40 cN.m); replacement screws are part number 1591MS100. The same size is also offered as 1591DTBU and 1591DTRD in the other translucent tints. Some chemicals can damage or weaken plastic, so check chemical compatibility before cleaning or modifying the case.
