Hammond 1551TGY 60x60x20mm Light Gray ABS Miniature Enclosure

The 1551TGY is a 60 x 60 x 20 mm (2.36 x 2.36 x 0.79 in) miniature enclosure molded in light gray (RAL 7035) ABS. It provides room for a PC board up to 54 x 54 mm and is suited to small electronic assemblies, interface circuits and potting applications that call for a neutral housing.

The body is molded from general purpose ABS plastic with 2 mm (0.08 in) walls and carries a UL94 HB flame rating. Lap joint construction between box and lid protects against dust and splashing water, and the enclosure is designed to meet IP54. PC board mounting bosses are molded into the interior and accept #2 self-tapping screws. The gray colour is specified as RAL 7035.

Outside, the 1551TGY measures 2.36 in x 2.36 in x 0.79 in (60 mm x 60 mm x 20 mm). The maximum PC board size is 54 mm x 54 mm, and the shipping weight is 0.05 lbs (0.02 kg).

Each assembly includes the box, the lid and 2 self-tapping #4 x 1/2" cover screws, nickel plated to match the enclosure; the recommended torque is 35-43 ozf.in (25-30 cN.m). Screws for securing the PC board are not included; the drawing lists part 1553WTS100 (Plastite self-tapping #2 x 3/16" (4.8 mm), pack of 100). The part is RoHS and REACH compliant and ships in a bag.

Hammond notes that some chemicals can damage or weaken ABS, including acetone, ketones, thread-locking compounds and cutting or tapping fluids, so check compatibility before cleaning or modifying. The enclosure can be factory modified (milling, drilling, printing) and solid models are available in .stp or .x_t format.
