Product Description And Features
The E3JK Retroreflective Photoelectric Sensor offers long sensing distances, ease of installation, and is particularly well-suited for detecting transparent or reflective objects. Its high-brightness LED indicators provide clear feedback for operation and adjustments, facilitating on-site setup. The sensor offers excellent electromagnetic interference resistance, making it suitable for complex applications in industrial environments.
This sensor supports a wide supply voltage range of 24-240 VAC/DC, ensuring stable operation across various industrial power systems. The built-in relay enhances control over load current, providing greater operational flexibility and reliability. Additionally, the adjustable sensing distance via the top knob and NO/NC switching enable easy adaptation to different control systems.
