Hammond 1591XXFSFLBK 221 x 150 mm Economy Flanged-Lid Black ABS Box

The Hammond 1591XXFSFLBK is the economy black version of the 1591XXF enclosure, the largest size in the 1591XX family of ABS plastic multi-purpose enclosures with PC board standoffs. It is intended for electronics designers, OEM engineers and technicians who need a flanged, general purpose plastic project box that holds a printed circuit board horizontally.

As an economy version it is molded from general purpose ABS that is not flame retardant (flame rating UL94 HB), and the lid is assembled with #4 x 1/2" self-tapping screws driven into fully plastic posts rather than brass inserts, giving a simpler assembly where a flame retardant rating is not required.

The ordering table lists the 1591XXF at 8.70 in (221 mm) long, 5.91 in (150 mm) wide and 2.52 in (64 mm) deep; the part page gives a nominal size of 8.7 in x 5.9 in x 2.3 in (221 mm x 150 mm x 58 mm). Inside, the drawing shows 204.47 mm [8.05 in] x 126.00 mm [4.96 in] with 57.34 mm [2.26 in] of inside height and a 3.00 mm [.12 in] wall. A board up to 204.00 mm [8.03 in] x 133.00 mm [5.24 in] fits in either the box or the lid, mounting on the integral standoffs that accept #4 x 1/4" self-tapping screws (not included).

Mounting flanges are integrated into the lid, extending overall length to 244.00 mm [9.61 in]. Four molded countersunk holes (Ø5.00 mm thru, 232.00 mm [9.13 in] spacing) allow installation to a wall or shelf, and an oval hole in each side of the flange lets the unit be strapped or hung with tie wraps. Unlike the smaller sizes, the 1591XXF is a universal type with PC board standoffs in both lid and enclosure as well as card guides.

The 1591XXFSFLBK is designed to meet IP54 against dust and splashing water, is RoHS and REACH compliant, and ships at 0.87 lbs (0.39 kg). Enclosures can be factory modified (milling, drilling, printing) and solid models are available in STEP or IGES.
