Integrated Photosensors

CNZ1402A/B

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.

Features

Built-in Schmitt circuit for strong noise-withstanding capability

Large output current

Open-collector output

Output transistors turn on and off (two types) when light is shined

CNZ1402A/CNZ1403A : Normally ON type

CNZ1402B/CNZ1403B : Normally OFF type
