Renishaw FORTiS enclosed linear absolute encoder series
Designed for use in harsh environments such as machine tools, the FORTiS enclosed linear absolute encoder design is built upon industry-proven RESOLUTE encoder technology and provides high resistance to the ingress of liquids and solid debris contaminants. It features an extruded enclosure with longitudinally attached interlocking lip seals and sealed end caps. The readhead body is joined to a sealed optical unit by a blade, which travels through the lip seals along the length of the encoder. Linear axis movement causes the readhead and optics to traverse the encoder's absolute scale (which is fixed to the inside of the enclosure), without mechanical contact.
