Omron E3S-DBN22 Photoelectric Sensor
Omron E3S-DBN22 is an NPN retro-reflective photoelectric sensor with an MSR function for transparent-object sensing from 0 to 0.5 m. Its 624 nm red LED provides the optical source, while the returned light from the reflector supplies the information required for switching. Smart Teaching supports setup for the required transparent target, while the NPN output interfaces with compatible industrial control circuits. The sensor operates from 10 to 30 VDC, uses an M12 connector, and supports load current up to 100 mA. Response time is specified at 0.5 ms. Within the E3S Series, the E3S-DBN22 provides the Smart Teaching NPN option. Explore short-range transparent sensors across Omron Sensing Range.

The Omron E3S-DBN22 Photoelectric Sensor uses retro-reflective sensing with an MSR function for transparent-object sensing across a range of 0 to 0.5 m. Its 624 nm red LED provides the optical source, while Smart Teaching supports sensitivity setup for the required transparent target. The sensor operates from 10 to 30 VDC and uses an M12 connector for detachable wiring. Its NPN output supports compatible industrial control circuitry, with load current rated up to 100 mA and maximum load supply voltage of 30 VDC. Current consumption is specified at 30 mA maximum at 24 VDC. Operate or reset time is 0.5 ms maximum, while orange light and green stability indicators provide visual status information.
For an Omron NPN transparent object sensor requiring Smart Teaching, MSR, and short-range reflector sensing, the corresponding model is the E3S-DBN22. Ambient-light resistance reaches 3,000 lx under incandescent light and 10,000 lx under sunlight. Operating temperature extends from -25 to 60°C, while storage ranges from -40 to 70°C without icing or condensation. Reverse supply polarity, output short-circuit, output reverse-polarity protection, and mutual-interference prevention are listed. Its specification also aligns with searches for an Omron Smart Teaching sensor and Omron 0.5 m NPN sensor. For an E3S NPN transparent-object model using the same 0 to 0.5 m range, see E3S-DBN21.
