For contactless SW, object detection
Overview
CNZ1402A/B and CNZ1403A/B are photocouplers in which a
high efficiency GaAs infrared light emitting diode as the light emitting
element, and a photodiode and a signal processing circuit as a light
detecting element are intergrated on a single chip.
The two elements are arranged so as to face each other, and objects
passing between them are detected.
