Hammond 1553DBK 147x89x25mm Black Handheld Enclosure, Grey Overmold

The 1553DBK is the large size D handheld enclosure in the 1553 Series, combining a black ABS case with a grey soft-sided overmold. At 147 mm long it offers the most board area of the 1553 range, suiting handheld instruments, meters and controllers with larger PCBs, displays or keypads.

The body is molded from general purpose ABS plastic with a UL94 HB flame rating and a soft plastic overmold for a comfortable grip. The top cover is recessed to take a membrane display or keypad, and PC board standoffs are molded into the case so the board aligns on the PCB bosses. As a single end panel version without a battery door, it is rated IP54.

Overall dimensions are 147 mm long, 89 mm wide and 25 mm deep (5.79 x 3.50 x 0.98 in); the nominal listed size is 5.8 x 3.5 x 0.98 in. The inner box is 140.24 mm long with an inner height of 19.50 mm, and the ordering table gives a maximum PC board of 139 mm x 74 mm (5.47 x 2.91 in).

The 1553DBK is supplied with the top, bottom, removable front plastic panel and 4 cover screws; the PC board is not supplied. Black 1553 enclosures use black screws.
