The 1590Z250PL is the inner mounting panel for the 400 x 230 x 180 mm 1590Z250 diecast aluminum enclosures in natural, black (1590Z250BK) and gray (1590Z250GY). It is a removable plate that lets integrators mount and wire components before fitting them into the sealed enclosure.

The panel is 16 gauge galvanized steel. The part page lists 14.96 in x 8.39 in x 0.06 in (380 mm x 213 mm x 2 mm), matching the enclosure's maximum P.C. board size of 380 x 213 mm. The drawing shows R12.70 corner radii and 1.59 x 45.0 degree chamfers.

It rests on the 1590Z250 internal mounting shelf, and the series ordering table pairs it with SCGM6-20 extra panel screws. Shipping weight is 2.09 lbs (0.95 kg), packed in a bag.

Per the drawing, enclosures can be factory modified and solid models are available in .stp or .x_t. The 1590Z250PL is RoHS and REACH compliant. Its parent 1590Z250 enclosure has 180 mm total depth and 170.60 mm inside depth per its drawing, giving tall components room above the panel inside an IP68, cUL US listed housing.
