WebDistance sensors (or proximity sensors) generally work by outputting a signal of some kind, (eg laser, IR LED, ultrasonic waves) and then reading how it has changed on its return. That change may be in the intensity of the returned signal or the time it takes the signal to return. WebHow does it work? The switch can generate and send ultrasonic pulses up to 10 meters. When an object reflects these pulses, the switch will detect the echoes and calculate the distance. Proximity Switch Symbol The proximity switch symbol diagram is similar to a mechanical limit switch.
