Hammond 1551GTBU 50x35x20mm Translucent Blue ABS Miniature Enclosure

The 1551GTBU is a translucent blue ABS plastic miniature hand held enclosure from the 1551 series, with a nominal size of 50 x 35 x 20 mm (1.97 in x 1.38 in x 0.79 in). It is intended for OEM engineers, electronics designers and installers who need a small general purpose box for mounting a compact printed circuit board or for use as a potting box.

The enclosure is molded from general purpose ABS plastic with 2 mm (0.08") walls and carries a UL94 HB flame rating. Colour is translucent blue, and the self-tapping lid screws are colour matched: black plated screws are supplied with this translucent blue version. Lap joint construction between box and lid protects against access of dust and splashing water, and the enclosure is designed to meet IP54.

The 50 x 35 mm footprint with 20 mm depth gives 44.73 mm of inside length and 16.00 mm of inside height, sized for a board up to 44 mm by 29 mm. Inside dimensions are 44.73 mm [1.76 in] long, 29.73 mm [1.17 in] wide and 16.00 mm [0.63 in] high. PC board mounting bosses are molded into the interior and accept #2 x 3/16" self-tapping screws (not included; part number 1551ATS100, nickel plated, pack of 100).

The 1551GTBU is supplied as box, lid and 2 cover screws (#4 x 1/2" self-tapping), with a recommended lid screw torque of 35-43 ozf.in (25-30 cN.m). It is RoHS and REACH compliant, packed in a bag, with a shipping weight of 0.03 lbs (0.01 kg). Some chemicals, including acetone, ketones, thread locking compounds and cutting fluids, can damage ABS, so check compatibility before use.
