The Omron E3FA-DP23 Photoelectric Sensor from Omron Corporation features a diffuse-reflective sensing method, 1 m sensing distance, and PNP open-collector output. Designed with a red LED light source and a robust plastic M18 cylindrical housing, it ensures consistent performance in industrial environments. Operating on a 10 to 30 VDC power supply, this model is part of the Omron E3FA Series widely used in industrial automation systems across India for precise and stable object detection.
Used in conveyor automation, packaging, and assembly systems, the E3FA-DP23 provides accurate detection without mechanical contact. Its compact plastic body and IP67/IP69K protection allow operation in environments exposed to dust and moisture. Engineers prefer it for tasks requiring quick response and reliable output, ensuring reduced downtime and stable operation in continuous industrial processes such as sorting, labeling, and filling lines.
The Omron E3FA-DP23 Photoelectric Sensor combines a compact design with a sensitivity adjustment function for flexible installation. For a similar sensor with NPN output, the Omron E3FA-DN23 Photoelectric Sensor offers the same diffuse-reflective method and sensing distance. For users preferring a pre-wired option instead of M12 connection, the Omron E3FA-DP13 2M Photoelectric Sensor provides a 2 m cable with PNP output. Alternatively, for longer-range detection using a reflector, the Omron E3FA-RP21 Photoelectric Sensor offers retro-reflective sensing up to 4 m with MSR function for reflective target stability.
The Omron E3FA-DP23 is designed for industrial reliability, supporting a fast 0.5 ms response time, IP69K protection, and stable performance under fluctuating lighting conditions. Its high durability and ease of setup make it suitable for demanding factory environments where precision and long-term stability are required. The E3FA Series reinforces Omronβs commitment to dependable automation sensors that deliver consistent results across Indiaβs industrial and manufacturing sectors.
