## **Switching characteristics** The optimum emitted light is selected automatically (at RGB variants). Static teach-in: light/dark setting is defined using teach-in sequence. Dynamic teach-in: switching output active on mark, if background is longer in the field of view during the teach-in. The switching threshold is set in the center between the background and the mark. Keylock (activation and deactivation): Press and hold the “+” pushbutton > 10 s. Teach-in failure: The Q-LED (yellow) flashes and all LEDs flash on the bar graph (green). **6** **Data sheet | 2026-03-24 23:34:06 Subject to change without notice** **CONTRAST SENSORS | SICK** **KTS-WB81141142ZZZZ | KTS** CONTRAST SENSORS KTS Core - setting the switching threshold (2-point teach-in) Suitable for manual positioning of the object to be detected, e.g. marks and background. ## **1.
