Precise Infrared Detection Technology: This IR photoelectric switch uses infrared light for sensitive object detection with nearzero delay, providing reliable automation control in industrial applications. Optimized Diffuse Reflection Sensing: The E3ZD61 diffusereflection sensor offers a 100 mm detection range and can accurately identify opaque objects as small as 75 mm for machine tools and conveyor systems. Wide Industrial Compatibility: Designed for 1224 V DC systems with NPN output, this infrared sensor switch is suitable for automatic doors, garage systems, aviation equipment, and harsh environments such as metallurgy and chemical plants. FastResponse NPN Output: Featuring an infrared LED light source and instant NPN output, this sensor ensures rapid, noninterfering detection and easy integration into automated machinery and safety devices. Use scenarios: On a conveyor line or machine tool setup, detect part presence within the 100 mm range and trigger downstream equipment or quality checks. In automatic doors or garage systems, sense approaching objects to actuate opening/closing safely and reliably. In harsh industrial environments like metallurgy or chemical plants, deploy as a robust 1224 V DC NPN sensing solution for safety interlocks and process automation.
