Hammond 1590WBB2FBK 120x94x38mm IP65 Black Diecast Box, Flanged Bottom

The 1590WBB2FBK combines the wide 1590BB2 body (120 x 94 x 38 mm nominal), a welded flanged bottom plate and a textured black powder-coat finish. Rated IP65 with its silicone gasket, it is a surface-mounting electronic instrument enclosure for applications where a dark, durable finish is wanted.

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 84.83 mm and 110.33 mm.

The listed size of 1590WBB2FBK is 4.7 in x 3.7 in x 1.49 in (119 mm x 94 mm x 38 mm), and the series ordering table gives a nominal 4.72 in (120 mm) x 3.70 in (94 mm) x 1.50 in (38 mm). A flanged bottom plate is welded to the box; the drawing shows 148.24 mm [5.836 in] overall across the flange, with the box 119.50 mm [4.705 in] long, 94.00 mm [3.701 in] wide and 39.25 mm [1.545 in] high including the plate. Inside, the drawing gives 113.77 mm [4.479 in] of length, 88.27 mm [3.475 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 1590BBGASKET holds two pre-formed, adhesive-backed silicone gaskets.

It is RoHS and REACH compliant, ships in shrink wrap at 0.64 lbs (0.29 kg), and solid models are available in .stp or .x_t.
