April 1, 2012 - HEIDENHAIN introduces LC 115 and LC 415 sealed Linear Encoders for use on machines with measuring lengths up to 4240 mm. Double sealing lips protect against contamination, and extrusions ensure high vibration resistance, making these encoders extremely strong on the accuracy front. When compressed air is introduced into the scale housing, a very effective seal between the two sealing lip pairs is the result. This protects the DIADUR graduation inside, which is responsible for the positioning accuracy, from contamination by dust, chips and coolant.
The Functional-safety (FS) encoders are available for the EnDat 2.2 interface and in the near future DRIVE-CLiQ interface. This means that these encoders can be used as single-encoder systems in safety-related applications, such as in axes with a linear motor. In addition to safe processing of the position values, these encoders provide fault exclusions for the loosening of the mechanical coupling for various types of mounting. The resolution of the LC 115 and the LC 415 is 1 nm.
