The Pi20 series is an integrated stainless steel circular grating with 20µm grating increments engraved on its surface, featuring an optical reference zero position. Available in three sizes (diameters of 75, 100, 300mm). The circular grating has excellent installation precision and includes a conical mounting system that reduces the need for parts with high tolerance requirements and eliminates eccentricity. It features a large inner diameter and flexible installation. The non-contact form eliminates the inherent reverse gaps, torsional errors (twist), and other mechanical errors of traditional enclosed grating.
Compatible with RX2 reading heads.
