The 1554APL is a galvanized steel inner panel for size A enclosures in the 1554 and 1555 families. It gives panel builders and OEM engineers a flat metal plate to mount components on inside the 52 mm x 50 mm x 40 mm (2.05 in x 1.97 in x 1.57 in) 1554A boxes: 1554AGY, 1554A2GY, 1554A2GYCL and 1554A2GYSL.

The panel is made of mild steel with a galvanized finish and measures 1.65 in x 1.73 in x 0.07 in (42 mm x 44 mm x 2 mm). The drawing confirms the 42.00 mm x 44.00 mm plate outline. It is supplied as an accessory and is ordered separately from the enclosure.

Use the 1554APL when you want to build up a sub-assembly outside the box and drop it in, or when components are easier to fix to steel than to the plastic body. It matches the inner panel listed for size A in the 1554 series ordering table, alongside the 1554AGASKET replacement gasket and SC576-50 lid screws for the same enclosures.

The part is REACH and RoHS compliant, and the part page lists UL file E65324. Shipping weight is 0.04 lbs (0.02 kg).
