The S80 series offers class 2 laser distance sensors with time of flight measurement provides the S80-Y0 and S80-YL0 proximity sensors with respectively a 0.3 - 4 m distance, or from 0.3 to 7 m with scalable range and the S80-Y1 and S80-Y2 retroflex sensors, with operating distances reaching 20 or 100 m, that measure the distance from a reflector mounted on the object. Models with two digital outputs, both the NPN and PNP, are available together with 4-20 mA analogue output and RS485 serial interface
