The new series of 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. The AT20’s industry-leading resolution and simple setup are ideal for glue-bead diameter applications and web guide applications in the printing and packaging markets. The AT20E Line Array Sensor is a cost-effective, compact solution specifically designed for edge detection applications. Unlike other solutions that are highly susceptible to contamination, the AT20E features a compact housing that can be mounted over the web so contamination is reduced and less downtime is required for maintenance.
