Hammond 1591XXDSBK 152x82x51mm Black Economy ABS Project Box

The 1591XXDSBK is the economy version of the 1591XXD enclosure: a black general purpose ABS case (flame rating UL94 HB, not flame retardant) whose lid is fastened with self-tapping screws into fully plastic posts. It gives OEM engineers and hobby or production builders a cost-conscious housing for a horizontally mounted printed circuit board, designed to meet IP54 against dust and splashing water.

Nominal enclosure size is 5.98 in (152 mm) long, 3.23 in (82 mm) wide and 2.01 in (51 mm) deep; the drawing gives overall dimensions of 152.43 mm [6.00 in] x 82.43 mm [3.25 in] x 50.50 mm [1.99 in], with an inside length of 145.40 mm [5.72 in], inside width of 75.40 mm [2.97 in] and inside height of 46.50 mm [1.83 in] over a 2.00 mm [0.08 in] wall. A PC board up to 145.00 mm x 75.00 mm [5.71 in x 2.95 in] fits in the box or in the lid.

The purchased assembly includes the box, lid and four #4 x 1/2" self-tapping cover screws in black, with a recommended torque of 35-43 ozf.in (25-30 cN.m). Replacement lid screws come in packs of 100 as 1591TS100BK (black) or 1591TS100 (nickel plated). Integral PCB standoffs in both the box and lid accept #4 x 1/4" self-tapping screws, which are not supplied (packs 1593ATS50 and 1593ATS100).

Internal sides are smooth for easy connector installation. For wall or shelf mounting, accessory ABS mounting flanges are sold separately (1591FDBK black, 1591FDGY grey). The 1591XXDSBK is REACH and RoHS compliant, ships shrink wrapped with a shipping weight of 0.25 lbs (0.11 kg), and can be factory modified (milling, drilling, printing); STEP and IGES solid models are available.
