The 1590Z162PL is the inner mounting panel for the 1590Z162 diecast aluminum enclosures, which measure 10.24 in (260 mm) long, 6.30 in (160 mm) wide and 3.54 in (90 mm) deep. It fits the natural 1590Z162, the textured black 1590Z162BK and the RAL 7001 gray 1590Z162GY, giving builders a removable plate for boards, DIN hardware or terminal strips inside the sealed box.

The panel is 16 gauge galvanized steel. The part page gives its size as 9.56 in x 5.81 in x 0.06 in (243 mm x 148 mm x 2 mm), and the drawing dimensions it at 242.70 mm [9.56 in] by 147.52 mm [5.81 in]. Those drawing figures match the maximum P.C. board figures listed for the 1590Z162 (242.7 mm and 147.52 mm), so the panel covers the full usable footprint.

The panel attaches to the enclosure's internal mounting shelf, and the series ordering table lists SCGM6-20 as the extra panel screws for this enclosure size. The 1590Z162PL is sold separately and ships in shrink wrap at 1.13 lbs (0.51 kg).

It is RoHS and REACH compliant, UNSPSC 39121301. Note that the taller 1590Z163 enclosure uses its own panel, 1590Z163PL, even though both boxes share the same 260 x 160 mm footprint.
