Block form factor and panel fit
The XS8C4A4DPN12 is a rectangular inductive sensor in a 40 x 40 x 117 mm block form. That 117 mm length is the dimension that determines clearance in a cable tray or machine frame — the 40 mm square face is what bolts to the bracket.
Peer compatibility check — XS8D1A1PBM12
The closest functional peer is the XS8D1A1PBM12, also an XS8 series block sensor. That unit is 80 x 26 x 80 mm — a different footprint entirely. The XS8C4A4DPN12's 117 mm length won't drop into a bracket drilled for the 80 mm body without a new mounting hole pattern.
