The AM4 series grating system is a compact grating designed for high - dynamic precision systems. The application of single - field scanning and low - latency subdivision processing endows it with excellent dynamic performance.

The read heads of the AM4 series are compatible with the M4 series ultra - thin stainless - steel grating scales with a pitch of 40μm. The expansion coefficient of the read heads is exactly the same as that of the substrate, eliminating the need for separate temperature compensation. The grating scales are corrosion - resistant and wear - resistant, and the high - strength rulings can effectively prevent the grating scales from being damaged, making them still applicable in harsh environments. The surface of the grating scales has no coating. When contaminated, the grating scales can be cleaned with solvents.
