PHOTOINTERRUPTER Photointerrupter P5747 High resolution photointerrupter P5747 consists of a photo IC, an LED and a mask slit enclosed in a C-shape plastic package. When used with a rotary disk (codewheel) or linear scale (codestrip), P5747 serves as a rotary or linear encoder that provides incremental two-phase digital outputs. P5747 uses the moire stripe slit method for incremental encoding. Light passing through the slits is detected by the 4-channel photodiode array in the photo IC and the detected signals are digitally processed. This method delivers a high resolution of 42 m equal to 1/4 of the slit pitch (169 m). Features Applications l High resolution: 42 m l Incremental two-phase digital output l TTL compatible l Head positioning for compact printers, etc. Absolute maximum ratings (Ta=25 C) Parameter Symbol Forward current *1 IF Pulse forward current *2 IFP Input (LED) Reverse voltage VR Max.
