Photoelectric Speed Sensor Encoder Coded Disc Code Wheel
Photoelectric Speed Sensor Encoder Coded Disc Code Wheel
The photoelectric encoder module consists of two discs located across each other. There is a light source on one disc and two light-receiving elements (photoresistors) on the other disc. Between these disks, there is a moving disc with evenly spaced slits. By rotating this moving disc, the light receivers A and B are alternately connected and disconnected. So, a square wave will be generated at the outputs. If you count these pulses, you can calculate the amount of rotation. In addition, there is a phase difference of 90 degrees between the two outputs A and B, so we can find the direction of rotation by checking which output is ahead of the other.
Technical Specification:
- Number of lines: 100 lines
- Outer diameter: 22mm
- Hole diameter: 3.5mm
- Thickness: 0.3mm
- Material: alloy steel
- Production process: laser cutting
- Supply voltage: 5V (3.3V is also available)
- Wiring: Red 5V black GND
- Output signal: 5Vp-p two-phase signal output
Features:
- Small and Easy to use the module
- It offers the fast response at a very good accuracy
- Two signal lines, one yellow, one blue
- Yellow and blue are two TTL level signals
Applications:
- Robotics industry
- Research and educational projects
