Omron E3S-DBP22 Photoelectric Sensor
Omron E3S-DBP22 is a PNP retro-reflective photoelectric sensor with an MSR function for transparent-object sensing from 0 to 0.5 m with the E39-R21 reflector. Its 624 nm red LED creates the optical path toward the reflector, while the PNP output sends the switching state to compatible control circuitry. The sensor operates from 10 to 30 VDC and uses an M12 connector for electrical integration. Load current is specified at 100 mA maximum, while current consumption is 30 mA maximum at 24 VDC. Response time is specified at 0.5 ms, with orange and green indicators supporting setup. Within the E3S Series, the E3S-DBP22 provides the short-range PNP configuration.

The Omron E3S-DBP22 Photoelectric Sensor uses retro-reflective sensing with an MSR function for transparent-object sensing across a range of 0 to 0.5 m with the E39-R21 reflector. Its 624 nm red LED establishes the optical path, while the PNP output supplies the switching state to compatible machine-control circuitry. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable connection. Current consumption is specified at 30 mA maximum at 24 VDC, while load current is rated up to 100 mA with a maximum load supply voltage of 30 VDC. Operate or reset time is specified at 0.5 ms maximum. Orange light and green stability indicators provide visual information for setup and operating status.
For an Omron short range transparent object sensor requiring PNP output, MSR, and M12 wiring, the corresponding model is the E3S-DBP22. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 60°C, with storage from -40 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, reversed output polarity, and mutual-interference prevention are included. PBT/ABS, PMMA, polyester elastomer, and PVC are among the specified materials. Its configuration also matches searches for an Omron 0.5 m PNP sensor and Omron transparent MSR sensor. For a longer PNP transparent-object version with sensing up to 3.5 m, see E3S-DBP21T.
