The 1594CWGY is the light gray, water-tight version of the C size in the 1594 Heavy Duty ABS Enclosures series. It is a rugged electronic instrument enclosure intended for mounting printed circuit boards, suited to OEM engineers and integrators who need a compact sealed housing for control electronics, sensors or interface boards.

The box and lid are molded in flame retardant ABS plastic carrying a UL94 V-0 flame rating, with a heavy duty thick-wall design (series average wall thickness 0.13 in / 3.3 mm; the part drawing shows 3.10 mm average) and a matte textured light gray finish. The part page lists an IP65 rating; the series literature states that water-tight versions have been tested to and meet IP66.

Listed size is 4.19 in x 2.6 in x 1.77 in (106 mm x 66 mm x 45 mm), with the series ordering table giving 106.5 x 66 x 45 mm. The drawing shows a narrowest inside dimension of 56.67 mm [2.231 in] and an inner box height of 39.60 mm [1.559 in], which sets the usable board envelope.
