The 1591AGY is a light gray 100 x 50 x 25 mm ABS plastic enclosure from the 1591 Series of multipurpose boxes with card guides, supplied as a plain rectangular box with no mounting flanges. It suits electronics designers, OEM engineers and integrators who need a compact project box for vertically mounted printed circuit boards, with 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 light gray enclosure it ships with standard nickel finish 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 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. Shipping weight is 0.11 lbs (0.05 kg).
The 1591AGY is supplied as box, lid, 4 cover screws, and pre-installed brass inserts. Recommended cover screw torque is 35.5-42.5 ozf.in (25-30 cN.m). Matching accessories include the 1591AC clear flame retardant polycarbonate lid, 1591Z6/1591Z50/1591Z100 PC board card adapters for horizontal board mounting, and 1599CLIP (black) or 1599CLIPGY (grey) nylon belt/pocket clips. The part is RoHS and REACH compliant, and the enclosure can be factory modified (milling, drilling, printing).
