The Omron E3FA-VP21 Photoelectric Sensor is a limited-distance reflective model from the Omron E3FA Series designed for reliable detection in industrial automation. It provides a 10–50 mm adjustable sensing distance, supports a 10–30 VDC power supply, and offers a PNP open-collector output. Built with an M18 plastic housing and an M12 connector, it includes a single-turn sensitivity adjuster. With IP67/IP69K protection and an operating range from −25°C to 55°C, this model ensures long-term stability in harsh industrial conditions.
Widely used in conveyor systems, packaging lines, and automated assembly stations, this sensor delivers stable output with quick response time. Its short sensing range allows accurate small-object detection, while the polarity-free red LED simplifies installation and reduces wiring errors. The durable housing and washdown-capable protection make it suitable for environments such as food processing and pharmaceutical automation where cleanliness and precision are essential.
The Omron E3FA-VP21 Photoelectric Sensor supports close-range precision sensing, while other variants provide specific operational advantages. The Omron E3FA-VN21 Photoelectric Sensor offers an NPN output version for controllers requiring sinking-type signals. The Omron E3FA-VP11 2M Photoelectric Sensor includes a pre-wired 2 m cable instead of an M12 connector, ideal for fixed installations. The Omron E3FA-DP21 Photoelectric Sensor uses a diffuse-reflective method with a 100 mm sensing distance, designed for larger target detection in short-range automation setups.
Reliable under varying light and environmental conditions, the Omron E3FA-VP21 provides engineers with consistent sensing for industrial operations. Its combination of compact design, sensitivity control, and IP69K protection ensures compatibility with multiple automation applications. Supported by Omron’s manufacturing quality, this model reinforces dependable performance across India’s industrial automation and process control systems.
