The 1591LSBK is a black 1591L plastic project box without mounting flanges, offering the deeper 39 mm body height of the 85 x 56 mm footprint. Card guides molded into all four side walls accept 1.5 mm (0.062 in) printed circuit boards, making it a natural fit for engineers and hobbyists who mount a board vertically inside a small handheld or bench enclosure.
This is the economy version, molded from general purpose ABS rated UL94 HB and not flame retardant. It keeps the lap joint box-to-lid construction that guards against dust and splashing water and is designed to meet IP54. The lid is secured with self-tapping screws driven into fully plastic posts, and the black finish comes with black screws.
Nominal size is 3.35 in x 2.2 in x 1.54 in (85 mm x 56 mm x 39 mm). The drawing gives an inside length of 78.71 mm [3.099 in], inside width of 51.71 mm [2.036 in] and inside height of 34.90 mm [1.374 in], with a guide height of 29.90 mm [1.177 in] and a slot width of 2.09 mm [.082 in].
Each 1591LSBK assembly includes the box, lid and 4 cover screws; recommended cover screw torque is 42-57 ozf.in (30-40 cN.m). Shipping weight is 0.12 lbs (0.05 kg), and the part is RoHS and REACH compliant. For horizontal board mounting, 1591Z card adaptors are offered.
