Transmissive Photosensors (Photo Interrupters)
CNZ1122, CNZ1128
Photo Interrupters
For contactless SW, object detection
Overview
CNZ1122 and CNZ1128 are a photocoupler in which a visible
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 : 1.2 mm
Fast response : t_r, t_f = 6 µs (typ.)
Using small package for saving mounting space (CNZ1128)
Small output current variation against change in temperature
