Reflective Optical Sensor CNY70

The CNY70 is a reflective sensor that includes an infrared emitter and phototransistor in a leaded package with a daylight blocking filter. These work great as close-range proximity sensors, tachometers, or line following sensors. Specifications Emitter: Emitter Wavelength: 950nm Forward Current (Max): 50mA Forward Voltage: 1.25-1.6V Power Dissipation: 100mW Detector: Detector Type: Phototransistor Filter: Daylight Blocking Collector Current (Max): 50mA Power Dissipation: 100mW Dimensions (Excluding Pins): Length: 7mm (0.3") Width: 7mm (0.3") Height: 6mm (0.24") Top View Pinout Resources CNY70 Datasheet CNY70 Library (Arduino Forums) CNY70 Tachometer example for Energia, instructions included for use with Arduino (from Frank Milburn) CNY70 Proximity Switch example for Energia, instructions included for use with Arduino (from Frank Milburn)
