Omron E3S-DCP21-IL2 Photoelectric Sensor
Omron E3S-DCP21-IL2 is a push-pull color-mark photoelectric sensor using diffuse-reflective sensing across a specified 10 ±3 mm working distance. Its RGB optical system uses red at 635 nm, green at 525 nm, and blue at 465 nm to evaluate printed marks and contrast differences. The push-pull output provides the switching signal to compatible machine-control circuitry, while teaching supports setup for the required mark condition. The sensor operates from 10 to 30 VDC, uses an M12 4-pin connector, and supports load current up to 100 mA. Response reaches 50 μs in 2-point teaching mode. Within the E3S Series, the E3S-DCP21-IL2 provides the IL2 push-pull configuration. Explore push-pull color mark sensors across Omron Automation Sensors.

The Omron E3S-DCP21-IL2 Photoelectric Sensor uses diffuse-reflective color-mark sensing across a specified distance of 10 ±3 mm with a 10 × 10 mm white-paper reference. Its optical system uses red at 635 nm, green at 525 nm, and blue at 465 nm to evaluate printed marks and contrast differences. A push-pull output transfers the switching state to compatible machine-control equipment, with the output specified High when the configured mark condition is recognized. The sensor operates from 10 to 30 VDC and uses an M12 4-pin connector. Load current is rated up to 100 mA with a 30 VDC maximum load supply. Response is 50 μs maximum in 2-point teaching mode and 150 μs maximum in 1-point teaching mode.
For an Omron push pull color mark sensor requiring RGB illumination and a 10 ±3 mm working range, the relevant model is the E3S-DCP21-IL2. Incandescent-light resistance is specified at 3,000 lx maximum. Operating temperature extends from -10 to 55°C, while storage ranges from -25 to 70°C. Power-supply reverse polarity, output short-circuit, and incorrect output connection protection are included. Diecast zinc, PMMA, ABS, and elastomers are among the specified materials. Its configuration also suits searches for an Omron push pull photoelectric sensor and Omron RGB teaching sensor. For another push-pull E3S color-mark configuration using the same optical wavelengths and sensing range, see E3S-DCP21-IL3.
