The 1555BGY is a square, general purpose ABS enclosure in the 1555 Series with a nominal size of 65 x 65 x 41 mm (the part page lists 2.6 x 2.6 x 1.6 in, or 66 x 66 x 41 mm). It is aimed at designers housing a small circuit board or DIN rail mounted device indoors, where a sealed, gasketed box is needed without outdoor or UL requirements.

ABS versions are molded from general purpose material with a UL94-HB flammability rating. They have been tested to and meet IP66, carry an IK07 impact rating per IEC 62262:2021, and are recommended for -20°C to +60°C (-4°F to +140°F). ABS versions are not UL listed; for a UL 508A listed, outdoor-capable box of this size, choose 1555B2GY in polycarbonate.

The lid closes with two piece tongue and groove construction over a one-piece replaceable silicone gasket that ships loose inside the enclosure. Four included M4 stainless steel machine screws thread into corrosion resistant inserts, are self captivating, and have a recommended torque of 43-57 ozf-in (30-40 cN-m). The light gray RAL 7035 styled lid provides a smooth recess for a label or membrane keypad.

The 1555BGY accepts a P.C. board up to 55.45 x 55.96 mm and has molded DIN rail mounting tabs; brass inserts, card guides and lid standoffs are not provided on size B. Two 4.00 mm wall-mounting holes are outside the gasket channel and also accept the 1554FT foot kit. Other accessories are the 1554BPL steel inner panel, 1554BGASKET gasket and 1554BCL clear lid. Shipping weight is 0.17 lbs (0.08 kg), shrink wrapped.
