Hammond 1590WR1FLBK Black 192x112x61mm IP65 Flanged-Lid Diecast Box

The 1590WR1FLBK is a water-tight diecast aluminum enclosure from the 1590 Series, built for electronics designers, OEM engineers and integrators who need a rugged instrument housing rated IP65. It offers a long 192 mm body, a listed maximum P.C. board size of 102.42 mm (length) by 182.42 mm (width), and six cover screws rather than the four used on most 1590 sizes.

Box and lid are made from diecast aluminum alloy, a material the manufacturer notes is tough yet easy to machine. Lap-joint construction where the lid meets the box helps keep out dust and splashing water. The textured black version is coated with a tough polyester powder paint that the manufacturer describes as a lasting finish, even after machining, and black cover screws are included to match.

The part page lists the size as 7.55 in x 4.39 in x 2.4 in (192 mm x 112 mm x 61 mm). On the drawing the box measures 191.80 mm [7.551 in] long, 111.60 mm [4.394 in] wide and 61.00 mm [2.402 in] high, with inside dimensions of 184.42 mm [7.261 in] by 104.42 mm [4.111 in] and an inside height of 56.50 mm [2.224 in]. Side walls have a low draft angle of 2° or less for easier PC board mounting, and the lid is 0.16" (4 mm) high.

This version has a wall-mounting flange integrated into the lid, bringing the overall length across the flange to 217.00 mm [8.543 in]; the box body itself keeps the same footprint as the unflanged model.

Each 1590WR1FLBK ships as a box, lid and 6 cover screws that thread into factory-tapped 6-32 UNC holes, plus a silicone gasket supplied loose inside the enclosure rather than pre-installed. The drawing recommends 25-30 cN.m [36-43 ozf.in] of screw torque with the gasket fitted. Replacement gaskets are sold as kit 1590RGASKET. It is RoHS and REACH compliant, and weighs 0.99 lbs (0.45 kg) shipped.
