| An optical switch consists of a light emitting diode that activates a phototransistor across an air gap. When the light beam is interrupted the output signal changes. When configured with a digital output signal they are ideal for switching and non-contact counting applications. When configured with an analog output signal they are ideal for precise position sensing. |
Optical Switch Applications: Optical Encoding, Limit Switching, Rotational Velocity Monitoring, Counter Circuits, Flow Metering, Linear Measurement, Precision Position Detection, Level Indication, Edge Detection. |
