The R507-164-000 is a formed inner mounting panel for the 160 x 320 mm size of the R100, R101 and R102 aluNORM Type 4X diecast aluminum enclosures (enclosure part numbers ending in -164). It gives OEM engineers, panel builders and electricians a steel plate on which to mount components, instead of fixing them directly to the enclosure casting.

The panel is made from 14 GA galvanized steel; the series ordering table lists aluNORM inner panels as 2 mm galvanized steel. Sized for the 160 x 320 mm enclosure, this panel provides a long, narrow mounting surface for components laid out in a line.

Listed size is 12 in x 5.7 in x 0.08 in (305 mm x 145 mm x 2 mm). The manufacturer's drawing shows an overall plate of 304.90 mm [12.00 in] by 144.90 mm [5.70 in]. Shipping weight is 1 lbs (0.45 kg), and the part ships in a box.

In the aluNORM accessory table, the 160 x 320 mm enclosure size pairs this panel with external feet R501-000-012 and the R510-000-000 hinge kit (set of 2). The R100 enclosures have internal mounting shelves along both sides with blind holes and grounding screws, and all sizes have inner blind holes. The R507-164-000 is RoHS compliant and REACH compliant. The drawing notes that factory modification (milling, drilling, printing etc.) is available on request and that solid models are available in .stp or .x_t format.
