Product Description And Features
The E3JK through-beam Photoelectric Sensor is an efficient and reliable detection device widely used in the field of industrial automation. Due to the separated transmitter and receiver, the sensor can achieve stable signal transmission over long distances, making it highly suitable for applications requiring extended detection ranges. Additionally, the sensor can effectively detect transparent and translucent objects and maintain excellent detection results under varying materials, colors, and surface reflection conditions.
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 adjustable sensing distance via the top knob and NO/NC (Normally Open/Normally Closed) switching enable easy adaptation to different control systems.
