For slim electronics that should show indicator lights through a tinted cover, the 1554FL2GYSL pairs a light gray (RAL 7035) polycarbonate base with a smoke polycarbonate lid. It shares the low-profile 120 x 90 x 45 mm nominal size of the 1554FL family.
This part is listed IP68, UL94 V-0 and cUL and UL 508A listed under file E65324. The series specification sheet gives polycarbonate versions NEMA 4, 4X, 6, 6P, 12 and 13 ratings; the manufacturer part page for this item prints "12 & 41" as its final value. The polycarbonate is UV stabilized for outdoor use, IK08 impact rated and recommended for -40°C to +110°C (-40°F to +230°F).
The drawing gives a 120.00 x 90.00 mm footprint with 45.45 mm overall height, and 112.99 x 82.99 mm of inside length and width with 39.35 mm of inside height. The part page lists a maximum PC board of 108.4 x 77.5 mm. Boards and inner panels fix to M3 brass inserts or standoffs for #6 self-tapping screws, card guides take 1.5 mm boards, and DIN rail tabs are molded in.
Four M4 stainless steel lid screws are included; they are self-captivating and thread into corrosion resistant inserts for repeated assembly. The one-piece silicone gasket is shipped loose for installation into the tongue and groove lid. Mount the 1554FL2GYSL through the 4X Ø4.30 mm holes outside the gasket channel, or fit the 1554FT foot kit. Shipping weight is 0.36 lbs (0.16 kg); REACH and RoHS compliant.
