Omron E3SCD66OMS is a diffuse reflective photoelectric sensor from the E3S-C series. Rated for 700 mm detection of opaque objects on a 10-30 VDC supply. Output is selectable NPN or PNP, with light-ON/dark-ON switching. Response time is 1 ms, load current 100 mA. M12 4-pin connector, IP67 rated for washdown areas.
Sibling range options
The E3SCD17OMS is mechanically identical (same housing and M12 connector) but offers 2 m sensing distance instead of 700 mm. If your application needs longer diffuse detection, that is a drop-in swap without rewiring. For a smaller footprint with cable termination, the E3SCD112MOMS (700 mm range, 2 m cable) uses a 20.4 mm wide housing — requires panel layout change but same electrical ratings.
