The LABL sensor combines small spot size and fast response to achieve high-speed label detection. The LABL is capable of detecting a wide variety of adhesive labels on various backings. The Learn key provides Standard, Thin, and Custom Learn. Custom Learn (LABL-2) provides a separate measurement on the gap and on the label to allow for optimal detection of difficult labels. Status LEDs provide a visual indication of learning and error conditions. Key lock mode is available to lock the Learn key. Remote learning input is provided. Light-ON / Dark–ON functionality is provided via the wiring connections (see M8 Connections section in manual). The sensor provides a discrete output that can be connected for NPN and PNP operation. A PLC can be used to monitor the status of the discrete output signal indicating label or gap presence as required.
