Omron E3S-DBP21 Photoelectric Sensor
Omron E3S-DBP21 is a PNP retro-reflective photoelectric sensor with an MSR function for transparent-object sensing across a range of up to 3.5 m when used with the E39-R8 reflector. Its 624 nm red LED provides the optical source, while Smart Teaching supports sensitivity setup for the required transparent target. 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 integration. Response time is specified at 0.5 ms, and load current is rated up to 100 mA. Within the E3S Series, the E3S-DBP21 provides the long-range PNP transparent-object option. Explore PNP transparent object sensors across Omron Industrial Sensing Products.

The Omron E3S-DBP21 Photoelectric Sensor uses retro-reflective sensing with an MSR function for transparent-object sensing across a range of 0 to 3.5 m when used with the E39-R8 reflector. Its 624 nm red LED provides the optical source, while Smart Teaching supports sensitivity setup for the intended transparent target. 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 30 mA maximum at 24 VDC, while load current is rated up to 100 mA with load supply voltage up to 30 VDC. Operate or reset time is specified at 0.5 ms maximum.
For an Omron PNP transparent object photoelectric sensor requiring MSR and sensing up to 3.5 m, the relevant model is the E3S-DBP21. 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 included. Its specification also suits searches for an Omron 3.5 m transparent sensor and Omron PNP MSR sensor. For an E3S NPN transparent-object configuration with a shorter 0 to 0.5 m sensing range, see E3S-DBN22.
