Omron E3FA-DP21 Photoelectric Sensor is a compact sensor for industrial automation featuring Diffuse-reflective, 100 mm sensing distance, PNP output, and 10 to 30 VDC supply. The E3FA-DP21 uses a red LED light source and an M18 plastic housing with an M12 connector option. This unit belongs to the E3FA Series and is specified for reliable object detection on assembly lines and machine I/O panels.
In conveyor and packaging operations the sensor provides stable presence detection and repeatable switching for part handling and throughput control. Its fixed sensitivity and 0.5 ms response time give predictable timing for PLC inputs, while IP67/IP69K protection supports washdown and dusty factory environments.
Omron E3FA-DP21 Photoelectric Sensor β related variations include Omron E3FA-DN21 which is similar but supplied with an NPN output for matching NPN PLC circuits, Omron E3FA-DP11 2M which provides the same diffuse-reflective sensing in a pre-wired 2 m cable format instead of an M12 connector, and Omron E3FA-RP21 which uses retro-reflective detection with extended range when paired with a reflector. Each linked model shows the specific connection type or output polarity difference to help select the correct interface for your machine.
Overall, this E3FA Series sensor package is designed for dependable operation in industrial settings where repeatable detection and connector flexibility matter. The combination of fixed diffuse sensing, IP67/IP69K protection, and a short response time makes the E3FA-DP21 suitable for conveyor checks, pick-and-place verification, and packaging end-of-line checks, offering predictable integration with PLCs and control systems. Omronβs reputation in photoelectric sensing supports long-term serviceability in India's manufacturing environments.
