Heidenhain Nonmagnetic Encoders Offer Versatility and Accuracy

Nonmagnetic linear and rotary encoders have been tested to withstand high-magnetic-field environments up to 6 T without influencing the machine environment. Commonly used in MRI machines, the mechanically stable encoders can function in strong magnetic fields without loss of accuracy or resolution. The linear series features a 20-µm graduation on glass, while digital versions, in which the digitizing electronics reside in the connector, can output resolutions to 50 nm. Three mounting configurations are available for the scanning unit.

Three mounting configurations are available for the scanning unit. The rotary series is a kit-style bearingless rotary encoder that includes an aluminum disk with various diameters and line counts, along with nonmagnetic scanning units to match each diameter. Offered in various sizes, the disk with a 20-µm graduation can be epoxied to the customer’s hub at the factory or on the user’s premises.
