Can the zero signal be as index signal？How to choose grating encoder?！

Whether linear encoder or its Z-axis encoder signals can be reached with the A \ B signals of the same accuracy, but the shaft encoder is a circle, and every linear encoders is a certain distance, the signal can be achieved with very high repeatability. Location may be the beginning of an ordinary proximity switch, and then find the closest signal Z (each looking in the same direction), when installed do not forget to look to its phase modulation and grating phase, and otherwise not allowed.

Depending on your choice of segmentation accuracy and resolution requirements. High precision natural to choose weekly lined with high accuracy is not high, there is no need to use high numbers lined the circular grating encoder.
