Omron E3RA-DP23 Photoelectric Sensor
Omron E3RA-DP23 is a PNP diffuse-reflective photoelectric sensor designed for direct object sensing across a distance of up to 700 mm. Its red LED sends light toward the target, while returned light provides the switching condition without requiring a separate reflector. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable wiring. Its cylindrical radial M18 body provides a compact mounting format, while Light-ON or Dark-ON operation can be selected according to the required machine logic. Response time is specified at 0.5 ms and current consumption at 25 mA maximum. Within the E3RA Series, the E3RA-DP23 provides the 700 mm PNP configuration. Related long-range diffuse photoelectric sensors can be explored across Omron Industrial Sensing Products.

The Omron E3RA-DP23 Photoelectric Sensor uses diffuse-reflective sensing in a cylindrical radial body for direct object sensing across a distance of up to 700 mm. Its red LED provides the optical source, while the PNP output transfers the switching state to compatible PLC inputs and machine-control circuitry. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable electrical connection. Current consumption is specified at 25 mA maximum. Light-ON or Dark-ON operation can be selected according to the required control logic, while response time is specified at 0.5 ms. The M18 body measures approximately 58 mm in length and uses ABS among the listed housing materials, providing a compact threaded mounting format for machine installations.
For an Omron PNP diffuse reflective photoelectric sensor requiring a longer 700 mm sensing range and M12 connection, the corresponding model is the E3RA-DP23. Its cylindrical radial format supports threaded installation where an M18 body is preferred. The specification also aligns with searches for an Omron 700 mm photoelectric sensor and Omron M18 PNP sensor. The 0.5 ms response supports applications where the switching state must change quickly as a target enters or leaves the sensing area. The longer sensing range makes this model suitable for object presence and position sensing where additional working distance is required. For a related E3RA PNP diffuse-reflective model with a shorter 300 mm sensing distance and M12 connector, see E3RA-DP22.
