optical linear scale with reference mark

Incremental Measurement with Reference Mark: Zero-Return for Absolute Origin

Linear S cale Advantages When using linear scales for position detection of linear axes, no additional mechanical transmission components need to be installed. The linear scale is directly installed on the slide plate, and it can collect the errors generated by mechanical transmission in real time. These errors can be corrected through the control system. The product is of an all-enclosed structure. The aluminum shell can protect the grating, the scanning reading head and the
