With SmartReflect Light Barriers, light beam is set up between sensor and machine part and when object interrupts beam, sensor is triggered. There must be background in sensing distance of sensor for operation. In this way, separate reflector becomes superfluous and common weak point is rectified. Special SmartReflect variants can use same principle to detect transparent objects such as bottles, trays, or even foils.
