Hammond 1590WB2FBK 112x61x38mm IP65 Black Diecast Box, Flanged Bottom

The 1590WB2FBK combines the 112 x 61 x 38 mm nominal 1590B2 body, a welded flanged bottom plate for surface mounting and a textured black powder-coat finish. With its silicone gasket installed it is rated IP65, giving OEM engineers and installers a surface-mounting electronic instrument enclosure with a durable dark finish.

The box and lid are made from diecast aluminum alloy, which is tough yet easy to machine, and carry a textured black finish of tough polyester powder paint that gives a lasting finish even after machining, with black screws included to enhance appearance. A lap joint where lid and box meet guards against dust and splashing water, and a side wall draft angle of 2° or less eases PC board mounting. The maximum P.C. board dimensions listed for this part are 53.17 mm and 104.77 mm.

The listed size of 1590WB2FBK is 4.43 in x 2.38 in x 1.48 in (113 mm x 60 mm x 38 mm), and the series ordering table gives a nominal 4.41 in (112 mm) x 2.40 in (61 mm) x 1.50 in (38 mm). A flanged bottom plate is welded to the box; the drawing shows 140.21 mm [5.520 in] overall across the flange, with the box 112.40 mm [4.425 in] long, 60.50 mm [2.382 in] wide and 39.00 mm [1.535 in] high including the plate. Inside, the drawing gives 106.77 mm [4.203 in] of length, 55.17 mm [2.172 in] of width and 33.50 mm [1.319 in] of height; the lid height is 0.16 in (4 mm).

As a watertight version it is designed to meet IP65 and includes a silicone gasket, supplied loose inside the enclosure rather than pre-installed. The purchased assembly includes box, lid and 4 cover screws that thread into factory-tapped 6-32 UNC holes. Recommended torque is 50-55 cN.m [71-78 ozf.in], or 25-30 cN.m [36-43 ozf.in] with the gasket fitted. Replacement gasket kit 1590BGASKET holds two pre-formed, adhesive-backed silicone gaskets.

It is RoHS and REACH compliant, ships in shrink wrap at 0.42 lbs (0.19 kg), and solid models are available in STEP or IGES.
