Hammond 1590WB2F 112x61x38mm IP65 Diecast Box, Flanged Bottom Plate

The 1590WB2F is the 1590B2-size watertight enclosure fitted with a welded bottom flange, so the box itself can be fixed to a flat surface. Nominally 112 x 61 x 38 mm in natural aluminum and rated IP65 with its silicone gasket, it serves installers and OEM engineers who prefer to mount an enclosure through its base.

The box and lid are made from diecast aluminum alloy, which is tough yet easy to machine, and carry a natural aluminum finish that is vibra finished for a smooth surface with no sharp edges. 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 1590WB2F 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 0.41 lbs (0.19 kg), and solid models are available in STEP or IGES.
