The 1591SF2BK is a black flame retardant ABS enclosure from the 1591S size of the 1591 Series, supplied with an accessory mounting flange attached to the bottom. Its body measures 4.33 x 3.24 x 1.73 in (110 x 82 x 44 mm), making it a practical housing for OEM electronics and circuit board assemblies that must be fixed to a panel or surface.
The bottom flange extends the overall length to 134.80 mm (5.307 in), with mounting holes spaced 123.30 mm (4.854 in) apart and a hole size of 4.50 mm (0.177 in). Overall height including the flange is 45.50 mm (1.791 in).
The box is molded from flame retardant ABS with a UL94 V-0 flammability rating. Lap joint construction guards against dust and splashing water, and the enclosure is designed to meet IP54. Because it is a black enclosure, it ships with black lid screws. Internal space is 103.77 x 75.87 x 39.90 mm (4.085 x 2.987 x 1.571 in), and card guides molded into every side wall hold 1.5 mm (0.062 in) printed circuit boards vertically, with a guide height of 34.90 mm (1.374 in).
The lid is secured with M3 x 10 mm Phillips machine screws threaded into pre-installed brass inserts, suited to repeated assembly and disassembly; recommended torque is 35.5-42.5 ozf.in (25-30 cN.m). The purchased assembly includes box, lid, 4 cover screws and the brass inserts. Optional accessories include the 1591SC clear polycarbonate lid and 1591Z adaptors for horizontal boards. RoHS and REACH compliant; shipping weight 0.27 lbs (0.12 kg).
