CNZ1102,CNZ1108
Photo Interrupters
For contactless SW, object detection
Overview
CNZ1102 and CNZ1108 are 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
Position detection accuracy : 1.2 mm
Large output current
Fast response : t_r, t_f = 4 µs (typ.) (CNZ1102)
6 µs (typ.) (CNZ1108)
Small output current variation against change in temperature
Small package used for saving mounting space (CNZ1108)
