Hammond 1590WB3BK 116x77x38mm IP65 Black Textured Diecast Box

The 1590WB3BK is the 1590B3-size watertight enclosure finished in textured black polyester powder paint. At 116 x 77 x 38 mm nominal with no mounting flanges and an IP65 rating once the supplied gasket is fitted, it is a practical electronic instrument enclosure for OEM products that need a dark, durable exterior.

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 69.67 mm and 108.67 mm.

The listed size of 1590WB3BK is 4.57 in x 3.03 in x 1.48 in (116 mm x 77 mm x 38 mm), and the series ordering table gives a nominal 4.57 in (116 mm) x 3.03 in (77 mm) x 1.50 in (38 mm). It has no mounting flanges, so the outside is a clean rectangle of 116.00 mm [4.567 in] by 77.00 mm [3.031 in] by 37.50 mm [1.476 in] on the drawing. Inside, the drawing gives 110.67 mm [4.357 in] of length, 71.67 mm [2.822 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 1590B3GASKET holds two pre-formed, adhesive-backed silicone gaskets.

It is RoHS and REACH compliant, ships in shrink wrap at 0.51 lbs (0.23 kg), and solid models are available in STEP or IGES.
