Hammond 1591DTRD 150x80x50 mm IR Red Polycarbonate Enclosure

The 1591DTRD is an IR Red polycarbonate enclosure in a larger 150 x 80 x 50 mm case. It gives designers a larger housing for electronics with infrared devices that work through the enclosure wall.

The IR Red version is almost totally transparent to infrared devices, making it a fit for circuits whose infrared devices sit behind the wall of the case. 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 1591DTRD 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 1591DTCL in the other translucent tints. Some chemicals can damage or weaken plastic, so check chemical compatibility before cleaning or modifying the case.
