Hammond 1590WKKBK 125x125x57mm IP65 Watertight Diecast Box, Black

The 1590WKKBK is a square 125 x 125 mm rugged diecast aluminum electronic instrument enclosure in a lower 57 mm height, built liquid-resistant for electronics exposed to dust and splashing water. It is the black watertight version with no mounting flanges, 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.

Outside, the enclosure measures 124.80 mm long, 124.80 mm wide and 57.00 mm high on the drawing. Inside there is 116.94 mm of length, 116.94 mm of width and 51.30 mm of height, and the listing gives maximum PC board figures of 116.38 mm and 116.38 mm. Side walls have a low draft angle of 2 degrees or less to make board mounting easier. Shipping weight is 0.94 lbs (0.43 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).
