The 2-in-1 solution transmits both switching and measuring information to the machine controller. The ODT 3C transmits measured values and extensive diagnostic data via IO-Link, for example temperature values, warnings and signal quality. It also has very good black/white behavior (< ± 3 millimeters at 150 millimeters). The scanning range can be set via the teach button, cable or IO-Link. Active ambient light suppression prevents faulty switching - even with direct light from LED hall lighting. LEDs indicate the status of the ODT 3C. Two independent switching outputs and sensor variants with warning output or small light spot (pinpoint) round off the range of functions.
