Incremental linear encoder ATOM™ RCLC

opticalnon-contactanalog

What is ATOM? ATOM is Renishaw's miniature non-contact optical incremental linear and rotary encoder system. Its innovative design combines miniaturisation with leading-edge signal stability, dirt immunity and reliability. This combination is unique in the market place and represents a significant advance in the performance and reliability of miniature encoders. ATOM is supplied in hi-flex cable and Flexible-Printed Circuit (FPC) variants with either 20 µm or 40 µm scale options. A range of interfaces is available including the standard Ri, a high-performance Ti and the compact open ACi interface. What is RCLC scale? RCLC is a glass spar scale which can be supplied in lengths to 130 mm featuring either 20 µm or 40 µm pitch incremental graduations. RCLC offers a total accuracy of ±3 µm and includes two reference marks: one at the scale mid-point and one at the end-of-travel. Selection is made by the orientation of the readhead relative to the scale. RCLC is laid onto the substrate with self-adhesive backing tape. The self-adhesive is formulated to allow for independent scale expansion to that of the substrate.
