The 1590WKFBK is a square 125 x 125 mm rugged diecast aluminum electronic instrument enclosure with a deep 73.50 mm inside height, built liquid-resistant for electronics exposed to dust and splashing water. It is the black watertight version with a flanged bottom plate, rated IP65 and listed by the manufacturer as a die-cast box, water-tight. It suits OEM engineers and integrators who want a sealed metal housing they can machine themselves, since diecast aluminum is tough yet easy to machine.

Box and lid are made from diecast aluminum alloy. Lap joint construction where lid and box meet guards against dust and splashing water, and this black version is coated with a textured polyester powder paint that keeps a lasting finish even after machining, with black screws included to match. A welded bottom flange plate extends beyond the box ends to provide mounting points.

Outside, the enclosure measures 125.00 mm long, 125.00 mm wide and 80.50 mm high on the drawing, with the flanged plate bringing overall length to 154.18 mm. Inside there is 118.10 mm of length, 118.10 mm of width and 73.50 mm of height, and the listing gives maximum PC board figures of 116.1 mm and 116.1 mm. Side walls have a low draft angle of 2 degrees or less to make board mounting easier. Shipping weight is 1.16 lbs (0.53 kg).

The purchased assembly includes the box, lid and 4 cover screws that thread into factory-tapped 6-32 UNC holes. The silicone gasket ships loose inside the enclosure rather than pre-installed. Recommended lid screw torque is 50-55 cN.m [71-78 ozf.in], or 25-30 cN.m [36-43 ozf.in] with the gasket fitted. A replacement gasket kit is 1590KGASKET, and stainless steel cover screws with O-rings are offered as 1590WMS100 or 1590WMS100BK (black).

The 1590WKFBK is RoHS and REACH compliant, ships in shrink wrap, and carries UPC 623980282923. The equivalent non-gasketed IP54 version is 1590KFBK. Solid models are available in STEP or IGES, and the enclosure can be factory modified with milling, drilling or printing.
