The 1590Z180PL is the optional steel inner mounting panel for the 180 x 180 mm 1590Z180 diecast aluminum enclosures in natural, black (1590Z180BK) and gray (1590Z180GY). It gives panel builders and OEM engineers a flat plate for DIN hardware, terminal blocks, PCBs or other components inside the sealed box, and it is sold separately from the enclosure.

The panel is 16 gauge galvanized steel. Listed size is 6.5 in x 6.54 in x 0.06 in (165 mm x 166 mm x 2 mm), and the drawing shows the 165.00 x 166.00 mm outline with R11.00 corner radii. Shipping weight is 0.7 lbs (0.32 kg).

The 1590Z180 box has an internal mounting shelf, and the series ordering table pairs this panel with SCGM6-20 extra panel screws, the 20-pack of copper M6 - 1.0 x 10mm ground hardware with washers shown on the enclosure drawing.

Taking components off the enclosure walls and onto a removable plate lets you wire the assembly on the bench before installing it. The part page lists an IP66 rating and RoHS and REACH compliance. Inner panels are optional and available for most 1590Z sizes; this one is sized for the 1590Z180, whose drawing shows 169.01 x 168.69 mm inside dimensions and notes that drawings are available for the steel inner panel.
