Linear motor feedback encoders

Published:  10 March, 2020

SICK has announced it has released safety-certified versions of its TTK70 and TTK50 magnetic absolute linear encoders with Hiperface interface, widening the opportunities for accurate, absolute motor feedback systems to be integrated into safe linear drives.

SICK says its TTK70S and TTK50S absolute linear encoders with Hiperface interface are now certified to SIL2 (IEC 61508) and PLd (EN ISO 13849) for safety-related motion supporting SLS (safely-limited speed) safety functions in safe drive controls.

The SICK TTK70 absolute linear encoder, together with the more compact SICK TTK50, are used for non-contact feedback of absolute position and speeds in linear axes. Offering long measurement lengths, the encoders are ideal for dynamic applications in linear direct drives or slide systems, wherever micron accuracy and high repeatability are demanded.
