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.

he 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. Plus, the AT20E features a high visibility white LED light source and no teach, program or menu activities, making setup virtually hassle free.

The cost-effective AT20D Line Array Sensor features a high visibility white LED light source that is ideal for diameter detection. The LED light helps identify black/white and minimal grayscale contrasts between the target and background, which allows the AT20D to read the target width to 0.1 mm. The high visibility white LED light also ensures high accuracy measurements independent of the materials’ reflective properties.
