The 1594DBK is the standard black version of the D size in the 1594 Heavy Duty ABS Enclosures series: a rugged electronic instrument enclosure ideally suited for mounting printed circuit boards. It fits OEM engineers, panel builders and integrators who want a durable housing with a machine-screw lid for a mid-size board.

Standard versions are molded in flame retardant ABS plastic that carries a UL94 V-0 flame rating. The heavy duty thick-wall design has a series average wall thickness of 0.13 in (3.3 mm), and the black matte textured finish corresponds to RAL 9011 on the drawing. The lid is secured with four M3 x 0.5 - 0.71 in (18 mm) long Phillips machine screws threaded into integral brass bushings.

The listed size is 5.18 in x 2.6 in x 2.17 in (132 mm x 66 mm x 55 mm); the series table gives 131.5 x 66 x 55 mm. On the drawing, the box is 131.50 mm [5.177 in] long and 66.30 mm [2.610 in] wide, with an inner box height of 49.30 mm [1.941 in] and a narrowest inside dimension of 56.97 mm [2.243 in]. Circuit board holders are available in the 1594Z Series.

The 1594DBK is rated IP54 and can be upgraded to IP66 by adding gaskets (1594DGASKET) and screws with o-rings (1594WMS100). Replacement standard machine screws are 1594MS100. It is RoHS and REACH compliant, weighs 0.3 lbs (0.14 kg) shipped, and can be factory modified by milling, drilling or printing.
