Product details

The OMRON E3S-CR61 is a retroreflective photoelectric sensor from the E3S-C series, with a right-angle head that sends the beam sideways for side-mount installations. It delivers 3 m maximum range, uses red light, and outputs both NPN and PNP signals from a single 2 m prewired cable. Selectable light-on/dark-on switching mode covers most PLC input requirements without extra logic.

Integration notes

Mounting: two M4 bolts through the rectangular zinc body (20 mm wide, 57 mm overall height). The right-angle face requires the bracket to hold the sensor body perpendicular to the target path. The 2 m non-terminated cable allows direct termination in a junction box; no connector to fuss with. Supply 10-30 VDC; load current limited to 40 mA. IP67 / NEMA 6P: hose-down safe, suitable for conveyor and packaging lines.

Frequently asked questions

What is the sensing method and range of the E3S-CR61?

The E3S-CR61 uses a retroreflective sensing method with a maximum sensing distance of 3 m. It requires a separate reflector (not included).

What outputs does the E3S-CR61 support?

It offers both NPN and PNP output circuits, selectable via the wiring, along with selectable Light On / Dark On switching mode.

Is the E3S-CR61 sealed for washdown environments?

Yes, it is rated IP67 and NEMA 6P, making it suitable for wet or dusty industrial environments.

How does the E3S-CR61 differ from the E3S-CR11?

Both are retroreflective sensors with the same range and electrical specs, but the E3S-CR61 has a right-angle sensor face (beam exits perpendicular to body), while the E3S-CR11 has a straight face (beam exits forward). This affects mounting orientation and bracket compatibility.
