Expanded capabilities the Q4X series laser distance sensors include an analog model to measure distance and a discrete model with exptended capability to detect clear objects and contrast changes. With the sub-millimeter distance change capability, the Q4X Analog model measures height and fill levels, complementing the presence or absence capability of the discrete model. This allows the sensor to support multiple applications including analog interfacing to the PLC with less programming. Master-slave synchronization avoids crosstalk in situations requiring more than one sensor, including using opposing sensors for thickness measurement. A teach mode has also been added to the original Q4X discrete laser sensor. This provides the ability to detect clear objects without need for a retroreflector. Additionally, the sensor can determine not only whether an object is present at the correct distance, but whether it is the correct object.
