CNZ1179
Photo Interrupter
For contactless SW, object detection
Overview
CNZ1179 is a photocoupler in which a high efficiency GaAs
infrared light emitting diode is used as the light emitting element,
and a high sensitivity phototransistor is used as the light detecting
element. The two elements are arranged so as to face each other,
and objects passing between them are detected.
Features
Highly precise position detection : 0.3 mm
Wide gap between emitting and detecting elements, suitable for
thick plate detection
Fast response : t_r, t_f = 6 µs (typ.)
Small output current variation against change in temperature
