Cross-reference note
If you're cross-referencing, the E3Z-D82K is a direct functional match — same sensing distance, light source, connection, and consumption. That's another SKU I don't need. The E3Z-D62K-M3J differs: it uses an M8 4-pin connector instead of the pre-wired cable, and its sensing distance is listed as 3 m (or 150 mm, depending on condition). The E3Z-D61K is a different variant with a short-range wide view (5 to 100 mm).
