The AT20 Line Array Sensors are the only line array sensors available that have diffuse mode, making them ideal for harsh environments where dirt and dust can interfere with retro-reflective sensors. These sensors are designed for both edge detection/positioning in web guide applications and for diameter measurement of targets on flat surfaces in the printing and packaging markets.

• Diffuse mode is less susceptible to contamination, helping to reduce downtime and labor costs while improving quality control
• Industry-leading resolution and high repeatability provide precise measurements
• White LED light source helps identify black/white and minimal grayscale contrasts between the target and background
• Cost-effective, compact alternative to ultrasonic or infrared specialty fork sensors and vision-based solutions
• Two versions available: AT20E for edge detection and AT20D for diameter detection

• web guidance
• automated glue detection
• double sheet detection
• gap detection
• width measurement
