The Omron E3RA-DP22 Photoelectric Sensor is a diffuse-reflective type sensor designed for precise detection tasks in industrial automation. It operates on a 10 to 30 VDC power supply and provides a PNP open collector output for easy connection with control devices. With a 300 mm sensing distance and M12 connector interface, it ensures dependable installation and signal transmission. Part of the Omron E3RA Series, this model uses a polarity-free red LED and offers high environmental resistance with IP67 and IP69K protection for stable performance in industrial conditions.
Used extensively in automation systems, this sensor performs well in packaging, material handling, and assembly applications. It accurately detects object presence, even under dusty or wet conditions, supporting reliable process control. The radial shape allows flexible installation on conveyors or robotic arms, while the single-turn adjuster makes on-site sensitivity tuning simple. With its quick 0.5 ms response time, it maintains consistent operation in dynamic production lines, enhancing overall equipment efficiency and productivity.
The Omron E3RA-DP22 Photoelectric Sensor belongs to a versatile family of models under the E3RA Series, offering varied configurations for industrial requirements. For similar functionality with NPN output, the Omron E3RA-DN22 Photoelectric Sensor provides identical sensing distance and specifications but supports NPN switching for alternate wiring preferences. The Omron E3RA-DP12 2M Photoelectric Sensor delivers the same PNP performance but comes with a pre-wired 2 m cable instead of an M12 connector. Alternatively, the Omron E3RA-RP21 Photoelectric Sensor offers a retro-reflective sensing method with a longer 0.1 to 4 m range using an E39-R1S reflector, ideal for extended detection distances. The Omron E3RA-DP22 ensures reliable short-range diffuse detection where precision and compact installation are essential.
The Omron E3RA-DP22 Photoelectric Sensor combines a robust plastic housing, radial configuration, and IP69K sealing to handle harsh industrial conditions. It operates efficiently between β25Β°C and 55Β°C, maintaining durability across temperature variations. Its stable red LED output and sensitivity adjuster simplify calibration and minimize downtime. Recognized under the trusted Omron brand, this E3RA Series sensor provides consistent detection performance for Indiaβs industrial automation environments, supporting reliable operation in manufacturing, logistics, and machinery control applications.
