CNZ1112

Transmissive Photosensors (Photo Interrupters) CNZ1111,CNZ1112 Photo Interrupters For contactless SW, object detection Overview CNZ1111 and CNZ1112 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 Highly precise position detection : 0.3 mm Wide gap between emitting and detecting elements, suitable for thick plate detection Fast response : tr, tf = 6 µs (typ.) Small output current variation against change in temperature Absolute Maximum Ratings (Ta = 25˚C) Parameter Symbol Ratings Unit Reverse voltage (DC) Input (Light Forward current (DC) emitting diode) Power dissipation VR IF PD*1 3 50 75 Collector current IC 20 Output (Photo Collector to emitter voltage VCEO 30 transistor) Emitter to collector voltage VECO 5 Co...
