Linear Encoders: Linear encoders measure the position of linear axes without intervening mechanical elements. This eliminates a series of potential error sources such as backlash, pitch error, or heating of the recirculating ball screw. Wherever rigorous position accuracy and high machining speeds are needed, linear encoders are essential.
Exposed Linear Encoders: Exposed linear encoders have zero mechanical contact between the scanning head and scale or scale tape. Applications include pick-and-place machines and direct drive systems, production and measuring equipment in the semiconductor industry.
