The PA circular grating is a kind of stainless steel grating. The outer ring surface is etched with the true single-track absolute position encoding. The data is read by the ABS series absolute read heads. It has good anti-pollution ability and can resist the pollution of light dust, scratches and oil stains.

It has excellent precision with a resolution of up to 0.019 arcseconds, making it suitable for high-precision application scenarios. The nominal grating pitch of 50 μm ensures excellent motion control performance.

Features such as a thin profile, large inner diameter, easy integration, low mass, and low moment of inertia make it widely applicable. It is a true absolute single-track circular grating. Resolutions of 18 bits, 23 bits, and 26 bits are available for selection.

The read head can read data in both forward and reverse directions, and the counting direction is determined by the direction of the grating scale. It has a loose installation tolerance, and the installation is simple and quick.
