Panasonic CNZ1105 Datasheet
Transmissive Photosensors (Photo Interrupters)
ON1105
Photo Interrupter
For contactless SW, object detection
Outline
ON1105 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
Fast response : tr, tf = 6 µs (typ.)
Small output current variation against change in temperature
