The 1590Z166PL is the steel inner mounting panel for the 1590Z166 diecast aluminum enclosures, which measure 14.17 in (360 mm) long, 6.30 in (160 mm) wide and 3.54 in (90 mm) deep. It fits the natural 1590Z166, the black 1590Z166BK and the gray 1590Z166GY and provides a full-length plate for circuit boards, relays and wiring components.

The panel is 16 gauge galvanized steel. Its part page size is 13.57 in x 5.71 in x 0.06 in (345 mm x 145 mm x 2 mm), and the drawing dimensions the outline at 344.70 mm [13.57 in] by 145.00 mm [5.71 in]. Those figures correspond to the maximum P.C. board size listed for the 1590Z166 (344.7 mm and 145 mm).

The panel fastens to the enclosure's internal mounting shelf. SCGM6-20 is listed in the ordering table as the extra panel screws for this enclosure. The 1590Z166PL is sold separately, packed in shrink wrap, with a listed shipping weight of 0.33 lbs (0.15 kg).

It is RoHS and REACH compliant and carries UNSPSC 39121301. Building your electronics on the panel first makes it easier to wire and test outside the box before installation.
