The kailh mouse encoder of CEN98 series is sealed mouse encoder,which can prevent the sundries from the mouse encoder destroy.
Mouse encoder(pulley) has three pins,which basic principle is utilize inside conduct follow the wheel movement and makes it has different conduct waveform.it also recognizes the movement direction and speed of wheel.
Conclusion,the connection ways of mouse encoder is:first lead foot VCC power,second and third are output,mouse encoder estimates the slide direction by the phase difference.Through time of duration output high level to estimate the speed of movement,in spite of the slide speed and direction,all the output pulse width are same
Bar-riel encoder uses the infrared ray to accept the signal ,the wheel works won’t has materiality contact,therefore it has good stability and long life.
When you mount the mouse encoder you need to notice below questions:
1. the height of mouse encoder mount
2. The type of mouse encoder
3. Whether it’s customed encoder for high-level mouse
