Hammond 1590WGBK 100x50x25mm IP65 Watertight Diecast Box, Black

The 1590WGBK is a slim 100 x 50 mm rugged diecast aluminum electronic instrument enclosure, built liquid-resistant for circuit boards that must be kept away from 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 100.00 mm long, 50.00 mm wide and 25.50 mm high on the drawing. Inside there is 95.23 mm of length, 45.23 mm of width and 21.00 mm of height, and the listing gives maximum PC board figures of 44.23 mm and 94.23 mm. Side walls have a low draft angle of 2 degrees or less to make board mounting easier. Shipping weight is 0.24 lbs (0.11 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 1590GGASKET, and stainless steel cover screws with O-rings are offered as 1590WMS100 or 1590WMS100BK (black).

The 1590WGBK is RoHS and REACH compliant, ships in shrink wrap, and carries UPC 623980791821. The equivalent non-gasketed IP54 version is 1590GBK. Solid models are available in STEP or IGES, and the enclosure can be factory modified with milling, drilling or printing.
