The 1590Z137PL is the inner mounting panel for the 1590Z137 diecast aluminum enclosure family. It gives electronics assemblers a flat steel plate on which to mount circuit boards, terminal strips or components before dropping the assembly into the enclosure.

The panel is steel; the drawing specifies 16 gauge galvanized steel, which the 1590Z series describes as its optional inner panel material. It measures 190 mm x 70 mm x 2 mm (7.48 x 2.76 x 0.06 in) and has a shipping weight of 0.32 lbs (0.15 kg). It is RoHS and REACH compliant.

The 1590Z137PL fits the natural 1590Z137, textured black 1590Z137BK and smooth gray 1590Z137GY enclosures, all of which have an internal mounting shelf. Those enclosures measure 200 mm (7.87 in) long, 80 mm (3.15 in) wide and 60 mm (2.36 in) in total depth with a 20 mm (0.79 in) lid depth. Extra panel screws for this size are listed as SCGM4-50.

Because inner panels in the 1590Z series are sold separately, order the 1590Z137PL alongside the enclosure when your build needs a removable mounting plate. Solid models are available in .stp or .x_t for layout work before drilling or mounting components.
