1. INTRODUCTION AND OVERVIEW RE08A is a rotary encoder kit which comes with a slotted disc (8 slots) and a simple interface sensor board. No further soldering is required. Rotary encoder is a sensor or transducer used to convert the data of rotary motion into a series of electrical pulses which is readable by controller. The slotted disc has a 35mm outside diameter with 8 slots that provides 16 transitions. The optical sensor is used to sense the 16 transitions of the slotted disc.

4. BOARD OR PRODUCT LAYOUT B C A D E Label Function Optical Sensor A +5 input supply B Ground/Negative of supply C Label Function Signal output/pulse output D Indicator LED E Optical sensor at “A” will detect the missing slot of disc when the disc rotate, further generate pulses at signal pin. Header pin at “B” is input supply. User should connect 5V (+) to this pin. Header pin at “C” is ground of 5V supply, or in other words, the negative terminal of supply.

5. INSTALLATION (HARDWARE) The hardware installation is divided into two parts. The first part is sensor board. Following figure shows example of wiring from sensor board to a microcontroller. 5V Microcontroller GND Counter Pulses generated 5V Time Simply connect the “+5” and “Gnd” to 5V supply, further connect the “Sig” pin to microcontroller input pin. Normally, the “Sig” will be connected to Counter/Clock/Encoder input for automatic counting purpose.

To get the rotation output from rotating shaft, the slotted disc must be placed within the space between optical sensor as shown in the following picture. Output shaft Slotted Disc Optical Sensor Note: Please DONOT break the slot of slotted disc during installation.

6. GETTING STARTED After installation, the rotary encoder is ready to count the rotation of output shaft. This information can further be calculation to obtain speed of output shaft or the velocity of motor. This kit is very simple and compact, connect to any microcontroller via the 3-pin header. The onboard infrared beam detects missing slots in a slotted encoder disk, and generates a pulse train. The generated pulses are a 0 to 5V output.
