SCHAUMBURG, Ill., July 15, 2013 — Heidenhain Corp.’s LIF400 series miniature incremental exposed linear encoders were designed for stage manufacturers or for those using linear motors in their machine design. With travel up to 1 m, the devices maintain a scale accuracy grade of ±3 μm. They are suitable for coarse and fine measurement applications (4 μm down to 10 nm of resolution), and for installations with limited space as well as for those with large mounting tolerance requirements. Because of its precisely measured layers of glass and reflective material, a new type of grating called Supradur offers very high tolerance to contamination such as oil, dust and fingerprints. Using optical limit switches, users can place limits anywhere directly on the scale, enabling it to be mounted closer to a motor than scales with magnetic switches. A separate homing track with an integrated reference mark allows the encoder to differentiate which side of the reference mark the scanning unit is located upon power-up.
