Part 1551LFLGY is a light gray (RAL 7035) ABS plastic enclosure with mounting flanges molded into its lid, making it ready to screw to a wall or hang with a tie wrap. It is part of the 1551 miniature hand held series, intended for small printed circuit boards and potting applications.
It is molded from general purpose ABS with a UL94 HB flame rating and 2 mm (0.08 in) walls. The lap joint between box and flanged lid resists dust and splashing water, and the enclosure is designed to meet IP54.
Each assembly includes the box, lid and 2 nickel plated #4 x 1/2 in self-tapping cover screws, colour matched to the grey plastic, with a recommended torque of 35-43 ozf.in (25-30 cN.m). Standoffs inside accept #2 x 3/16 in board screws, available separately as 1551ATS100.
The 1551LFLGY is RoHS and REACH compliant and ships in a bag at 0.05 lbs (0.02 kg). Its black counterpart is 1551LFLBK.
