The 1550WGBK is a black watertight diecast aluminum enclosure from the 1550 Series, measuring 8.74 in (222 mm) x 5.75 in (146 mm) x 2.17 in (55 mm) including the lid. It is supplied with an IP66 EVA foam gasket and is rated IP66, making it a practical housing for electronics builders, OEM engineers and integrators whose circuits face dust and water.
The 1550G size provides a large 222 x 146 mm footprint at 55 mm overall height, and shares its footprint and gasket kits with the 105 mm tall 1550H. Per the drawing, the inside box measures 215.46 mm [8.48 in] long by 139.46 mm [5.49 in] wide with 51.10 mm [2.01 in] of inside height, and the box stands 51.00 mm [2.01 in] tall without the 4 mm lid.
The rugged die-cast alloy is tough yet easy to machine. It is finished in tough satin black polyester powder paint that lasts even after machining, and black lid screws are included for a matched assembled appearance. Walls have no internal ribs, so connectors fit without interference or extra milling, and the low side wall draft angle (2° less) makes PC board mounting easier. The lid is secured by M3.5 x 0.6 x 12 mm stainless steel Phillips head screws into factory tapped holes.
The EVA foam gasket ships loose inside the enclosure and is rated up to 65°C (149°F); installed properly with the lid screws torqued at 55 cN.m the 1550WGBK is designed to meet IP66. Spares are 1550GEGASKET (IP66) and the silicone IP67 upgrade is 1550GSGASKET. The same size without a gasket is 1550G (natural) or 1550GBK (black).
RoHS and REACH compliant, shipped in shrink wrap at 1.28 lbs (0.58 kg). UPC 623980057767, UNSPSC 39121301. Solid models are available in .stp or .x_t, and the enclosure can be factory modified (milling, drilling, printing).
