Hammond 1551SNAP3GY 60x60 mm Unvented Light Gray ABS Snap-Fit Enclosure

The 1551SNAP3GY is a square, unvented miniature enclosure in light gray, designed for IoT and general purpose electronics. With a nominal 60 x 60 mm footprint and 20 mm depth, it houses a PC board up to 52.9 x 54 mm in a low-profile package suited to wall mounting.

The enclosure is molded in ABS plastic rated UL94 HB and is designed to meet IP30. Because it is the unvented version, the housing is closed, and the snap-fit base and cover can be opened and closed repeatedly with no hardware required.

Overall size is listed as 2.36 in x 2.36 in x 0.79 in (60 mm x 60 mm x 20 mm), with a drawing height of 20.30 mm [.80 in] for the assembled enclosure. Four PC board standoffs are molded into the interior and accept #2 self tapping screws; Hammond recommends #2 x 3/16" self tapping screws, sold separately as 1553WTS100 (pack of 100), tightened to a recommended torque of (21-28) ozf.in / (15-20) cN.m. Shipping weight is 0.06 lbs (0.03 kg).

• Assembly hooks on the base
• Wall-mounting slots on the base
• A knockout on the base that can be removed with a screwdriver for wire entry (cable punch-out 15.00 x 8.00 mm [.59 x .31 in])
• Snap-fit closures on base and cover

The part is RoHS and REACH compliant. The same size is also offered as the vented 1551V3GY. Hammond notes that some chemicals, including acetone, ketones, thread locking compounds and cutting fluids, can damage ABS plastic, so check compatibility before cleaning or modifying the enclosure.
