The 1554F2GY is a light gray (RAL 7035) polycarbonate enclosure with a matching gray polycarbonate flat lid, sized at a nominal 120 x 90 x 61 mm. It is built for OEM engineers, panel builders and field technicians who need a sealed, UL listed housing for a printed circuit board or DIN rail mounted components, indoors or out.
Polycarbonate versions of the 1554 series are UV stabilized for outdoor use, and the solid gray material carries a UL94-5VA flame rating. The lid seals through a two piece tongue and groove joint with a one-piece, replaceable silicone gasket, which ships loose inside the box for you to fit. Four included M4 stainless steel lid screws thread into corrosion resistant inserts, are self-captivating, and are designed for repeated opening.
The drawing shows an overall footprint of 120.00 x 90.00 mm and a height of 60.50 mm, with an inside length of 112.91 mm, inside width of 80.91 mm and inside height of 54.50 mm. The part page lists a maximum PC board of 77.47 x 108.41 mm. Inside you get M3 brass inserts, standoffs that accept #6 self-tapping screws, vertical card guides for 1.5 mm boards and molded DIN rail tabs; the optional 1554FPL steel inner panel is ordered separately.
For protection, this size is listed at IP68 and NEMA 4, 4X, 6, 6P, 12 and 13, with an IK08 impact rating and a recommended operating range of -40°C to +110°C. The 1554F2GY is cUL and UL 508A listed under file E65324, REACH and RoHS compliant, and ships shrink wrapped at 0.42 lbs (0.19 kg). Four Ø4.00 mm wall-mounting holes sit outside the gasket channel and also take the 1554FT foot kit.
