Hammond 1591AFLBK 100x50x25mm Flanged Lid Flame Retardant ABS Box, Black

The 1591AFLBK is a black 100 x 50 x 25 mm ABS plastic enclosure from the 1591 Series, built with wall-mounting flanges molded into the lid so it can be screwed directly to a wall, panel or chassis. It is aimed at OEM engineers, integrators and electronics builders who want a small housing for vertically mounted printed circuit boards, using card guides molded into all side walls that accept 1.5 mm (0.062") thick boards.

This is a standard version molded from easy-to-machine flame retardant ABS plastic rated UL94 V-0. The lid is secured with M3 x 10 mm Phillips machine screws threaded into integral brass bushings, which suits applications needing repeated assembly and disassembly. Lap joint construction between lid and base protects against dust and splashing water, and the enclosure is designed to meet IP54. As a black enclosure it ships with black screws.

Nominal size is 3.94 in x 1.97 in x 0.98 in (100 mm x 50 mm x 25 mm). The drawing gives outside dimensions of 100.00 mm [3.937 in] by 50.00 mm [1.969 in], an overall length of 125.34 mm [4.935 in] across the flanged lid and an overall height of 24.80 mm [.976 in], with inside dimensions of 93.83 mm [3.694 in] long, 43.83 mm [1.726 in] wide and 20.90 mm [.823 in] high.
