The 1590WPFL is a watertight diecast aluminum enclosure in the 1590P size, 6.03 x 3.27 x 1.98 in (153 x 83 x 50 mm), with a flanged lid for wall mounting and internal card guides. Finished in natural aluminum and designed to meet IP65, it suits engineers who want to slide a circuit board into guides inside a sealed, surface-mounted box.

The box and lid are diecast aluminum alloy, which is tough yet easy to machine, and this part has an unpainted natural aluminum surface that is vibra finished for a smooth surface with no sharp edges. Lap joint construction where lid and box meet helps keep out dust and splashing water, and the low side wall draft angle (2° or less) makes P.C. board mounting easier.

The drawing gives an inside length of 146.29 mm (5.759 in), inside width of 73.98 mm (2.913 in), inside height of 45.30 mm (1.783 in) and a guide height of 41.73 mm (1.643 in). The lid fastens with four M3.5 x 0.6 cover screws.

A silicone gasket is supplied with this liquid resistant enclosure, loose inside the box rather than pre-installed. The purchased assembly includes the box, lid and 4 cover screws (4X M3.5x0.6 threads); recommended torque is 50-55 cN.m [71-78 ozf.in], or 25-30 cN.m [36-43 ozf.in] with the gasket. The part is RoHS and REACH compliant, and the enclosure can be factory modified (milling, drilling, printing).
