Maintenance teams planning replacements for E3S-DCP21-IL2 frequently review Omron SMPS 24V 10A, E3Z D61 2M and Omron Sensors to prevent downtime, checking availability and compatibility with existing systems.
Omron E3S-DCP21-IL2 Photoelectric Sensor
The Omron E3S-DCP21-IL2 Photoelectric Sensor is a Color Mark Diffuse-reflective (mark detection) featuring a 10Β±3 mm sensing distance, Push-pull output, and M12 connector for precise color mark detection. It operates on a 10 to 30 VDC power supply with 960 mW maximum power consumption and belongs to the Omron automation range under the Omron Photoelectric Sensors category and the Omron E3S Series. Equipped with Red (635 nm), Green (525 nm), and Blue (465 nm) LED light sources, it offers a 50 ΞΌs response time (2-point teaching mode), 150 ΞΌs (1-point teaching mode), and durable IP67 protection for stable industrial performance.

Built for demanding automation environments, the Omron E3S-DCP21-IL2 Photoelectric Sensor uses a diffuse-reflective sensing method and combines red, green, and blue LED light sources to detect subtle variations in printed color marks. Its sensing range of 10 Β±3 mm is ideal for applications such as packaging, labeling, and printing lines. With selectable 1-point or 2-point teaching modes and a response time as fast as 50 Β΅s, it offers high-speed and accurate detection.
This model supports push-pull output and operates on a 10 to 30 VDC power supply. The M12 connector ensures quick and secure integration into existing systems, while protection features such as reverse polarity, short-circuit, and incorrect connection safeguards make it highly durable. Designed with a nickel-plated diecast zinc body and rated IP67, the sensor is resilient against dust, water, and vibration. Weighing approximately 370g, the E3S-DCP21-IL2 is trusted by engineers seeking consistency in mark detection under fast-paced, multi-color environments.
