Hammond 1590WFFLBK 188x188x67mm Black Watertight Box, Flanged Lid

The 1590WFFLBK is the water-tight version of the 1590F, a square diecast aluminum enclosure measuring 7.4 in x 7.4 in x 2.64 in (188 mm x 188 mm x 67 mm). It has a wall-mounting flange integrated into the lid. The wide, low profile suits OEM engineers and integrators housing larger PC boards and instrument electronics that must be protected from dust and splashing water.

Box and lid are die-cast aluminum alloy, tough yet easy to machine, and meet in a lap joint. This water-tight version is designed to meet IP65 and includes a silicone gasket supplied loose inside the enclosure, not pre-installed. The textured black finish is a tough polyester powder paint that gives a lasting finish even after machining, and black screws are included to match.

Maximum P.C. board size is listed as 174.91 mm x 174.91 mm. The drawing shows an inside width of 178.50 mm [7.027 in] and an inside height of 61.51 mm [2.422 in]. Overall length across the lid flange is 217.00 mm [8.543 in]. Side walls have a draft angle of 2° or less for easy board mounting, and the lid is 0.16" (4 mm) high.

The 1590F size is one of the few in the series secured by eight cover screws, supplied threaded into factory-tapped holes and taking 6-32 x 1/2" screws. Recommended torque is 50-55 cN.m [71-78 ozf.in], or 25-30 cN.m [36-43 ozf.in] with the gasket. Optional items include the 1590FGASKET replacement gasket kit and 1590WMS100BK liquid resistant screws with O-ring.
