The QS18 Expert opposed-mode sensor with IO-Link is a compact, versatile photoelectric sensor with infrared and visible beam emitter/receiver pairs with a range of 20 m (66 ft). The economical sensor is now available with superior light immunity, crosstalk avoidance, and IO-Link communication.
The new QS18E offers superior ambient light immunity to prevent unintentional triggering and prevents the sensor from being tricked by ambient light sources, such as a lightbulb, flashlight, or other light-emitting industrial sensors used in the intelligent factory and automated distribution centers. In other words, the receiver will only be triggered by its own emitter.
Another key benefit of the QS18E Opposed-Mode sensor is crosstalk avoidance provided by optical synchronization. This means that each sensor can be set to one of 3 different frequency channels, so that three sensor pairs can be mounted side-by-side with no crosstalk.
Expert TEACH and SET methods ensure optimal gain and threshold for all applications, especially for high-speed or partial beam block (low contrast) applications. Configure the receiver using any of six TEACH or SET methods to define the sensing limits. Choose from Two-Point Static and Dynamic TEACH methods, plus Window, Light, and Dark SET and Opaque Mode for reliable long-range detection of very dark objects.
IO-Link is a point-to-point communication link between a master device and sensor. Use IO-Link to enable remote input function to configure the senor remotely. There are many advantages of an IO-Link system, including standardized and reduced wiring, increased data availability, remote configuration and monitoring, simple device replacement, and advanced health diagnostics.
The new QS18E opposed-mode sensor allows users to more specifically determine how the senor will perform. For example, users can use hysteresis sensitivity, on and off delays, offset percentages from teach, and response speeds. In addition, users can set the sensor to Push Pull, PNP, or NPN so that one sensor can be used for any output type. Furthermore, users can control health thresholds to define when to trigger an alert for cleaning or maintenance or signal when a runtime threshold is reached.
