incremental linear encoder / optical / non-contact / miniature

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.

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.
