Operating Principle
A 650 nm laser diode emits a collimated beam onto the target; diffused light returns to a high-speed PIN photodiode. After TIA amplification and filtering, a comparator with temperature compensation drives a push-pull stage. A multi-turn potentiometer sets the distance threshold within 15–200 mm. Laser class 1 (IEC 60825-1).
