These laser sensors offer precise positioning of small parts, as well as dark, transparent or complex-shaped objects. Their background evaluation mode makes them a suitable choice for detecting highly reflective or shiny parts. Their intelligent ambient light suppression function allows them to filter out interference and ambient light. The different detection and processing modes enable detection of complex-shaped objects. Their enhanced background suppression capability allows them to detect and measure dark and transparent objects, such as plastic film or products. For teach-in, the switching point and the analog output curve can be taught using a push button key on the sensors if not using IO-Link.
