The 1591RTBK is a 120 x 80 x 59 mm black ABS enclosure whose interior is masked and sprayed with an EMI/RFI copper conductive coating. The tall 59 mm depth on a 120 x 80 mm footprint suits electronics builders who need shielding for boards carrying taller components.

Each enclosure part is molded from flame retardant ABS plastic, a material carrying a UL flammability rating of 94V-0, in a smooth black finish with black screws. The interior of each part is specially masked and sprayed with an RFI/EMI copper conductive coating, and the coating manufacturer specifies an attenuation of more than 75 dB from 1 MHz to 1 GHz. The enclosure is designed to meet IP54 and is listed as RoHS and REACH compliant.

The nominal size is 120 x 80 x 59 mm, and the drawing gives overall dimensions of 120.00 x 80.20 x 58.90 mm. The inside height of 54.80 mm and card guide height of 49.80 mm allow a vertically mounted board with generous component clearance. Internal side walls include molded-in card guides with a guide height of 49.80 mm and a slot width of 2.06 mm, making the case well suited to vertical mounting of printed circuit boards.

The purchased 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, which suits applications where repetitive assembly and disassembly are required; recommended torque is 35.5-42.5 ozf.in (25-30 cN.m). The matching plastic flange kit for the 1591RTBK is 1591FTBK. Some chemicals can damage or weaken plastic, so check the manufacturer's chemical resistance guidance before using solvents, thread lockers or cutting fluids.
