Rectangular luminescence sensor LMS

LMSfor packaging machines

The LMS sensor combines small spot size and fast response to achieve high-speed operation capable of detecting a wide variety of luminescent marks and objects such as wood, adhesives, UV inks and optical brighteners on various surfaces over a range of 50 grayscale levels. The modulated UV light source in the LMS is focused to a 3-5 mm spot and directed toward a target. The diffused light returning to the sensor is measured. When the level is equal to or exceeds the threshold the discrete output changes state. Due to the fast response of the sensor, it is suitable for use in high-speed applications. The sensor provides a discrete output that automatically configures to NPN and PNP. A PLC or a computer can be used to monitor the status of the discrete output signal.
