The 1557F2BK is a black polycarbonate watertight enclosure from the 1557 Series, sized 6.3 in x 6.3 in x 1.77 in (160 mm x 160 mm x 45 mm). It suits OEM engineers and integrators who need a low-profile, sealed housing for printed circuit boards, with room for a board up to 147.5 mm x 147.5 mm.
The polycarbonate body is UV stabilized for outdoor use and is cUL and UL 508A listed under file E65324. The part page lists IP68 and NEMA 4, 4X, 6, 6P, 12 & 13, and polycarbonate versions carry an IK08 impact rating per IEC 62262:2021 with a recommended operating range of -40°C to +110°C (-40°F to +230°F). The flame rating shown for this part is UL94 V-0.
A gasketed lid with two piece tongue and groove construction and a one piece high temperature silicone gasket guards against oil, dust and water. Four stainless steel M4 cover screws thread into corrosion resistant bushings, so the lid can be opened and closed repeatedly; the recommended cover screw torque is 71-85 ozf-in (50-60 cN-m). Inside, the cavity measures 151.02 mm [5.95 in] square with 38.80 mm [1.53 in] of height.
Every 1557F2BK ships with the box, lid, 4 cover screws, the preformed silicone gasket, 4 rubber feet, 4 wall mount feet and 4 wall mount foot screws. Use it on a tabletop, flush on a wall with the feet acting as keyhole slots, or in a heavy duty wall flange configuration; pole mount kits PMB6687KIT3 and PMB6687KIT4 fit this profile. Shipping weight is 0.71 lbs (0.32 kg).
