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. It features a high-brightness LED indicator for easy visual confirmation during setup and adjustment. With excellent electromagnetic interference resistance, the sensor is well-suited for use in demanding industrial environments.
The sensor supports a wide supply voltage range of 24-240 VAC/DC, greatly enhancing its adaptability across diverse applications and ensuring stable operation in various industrial settings. The built-in relay also provides greater control over load current, improving both operational flexibility and reliability. Additionally, the sensor allows for NO/NC (Normally Open/Normally Closed) switching via rear wiring, offering further adaptability to different control systems.
