Hammond 1551WHGY 35x60x22mm IP68 Watertight Enclosure, Gray

The 1551WHGY is a watertight miniature enclosure without flanges, moulded from light gray polycarbonate with a satin texture finish. Part of the 1551W series, it is designed to meet IP68 and is suitable for outdoor use, which makes it a practical housing for small printed circuit boards in OEM products, sensors and field electronics that must be protected from water and dust.

Nominal size is 1.38 in x 2.36 in x 0.87 in (35 mm x 60 mm x 22 mm), with the 22 mm depth including the lid. The maximum PC board size is 54.5 mm x 29.5 mm (board not supplied), and PC board standoffs are moulded into the interior for easy installation; they accept #2 self-tapping screws such as 1553WTS100 (#2 x 3/16" Plastite, 4.8 mm, pack of 100), with a recommended torque of (21-28) Ozf.in / (15-20) cN.m.

Each purchased assembly includes the box, lid, a replaceable silicone gasket and four #4 Plastite self-tapping cover screws. Recommended cover-screw torque is (71-100) Ozf.in / (50-70) cN.m. Replacement gaskets are sold as 1551WHGASKET (2-pack), and stainless steel replacement cover screws are available as SC509-50 (#4 x 3/8" Plastite, 9.5 mm, pack of 50).

The polycarbonate is rated UL94 V-0, and the part is RoHS and REACH compliant. The same size is offered with integrated wall-mounting flanges as 1551WHFLGY, and in black as 1551WHBK. Hammond can factory modify these enclosures (milling, drilling, printing), and solid models are available in .stp and .x_t formats. Avoid strong solvents, thread lockers and cutting fluids, which can damage polycarbonate.
