Magnetic linear encoders

Ultra high speed measurement for linear direct drives

Your Benefits

  • The STL/ETL70 requires no reference run, meaning it is immediately ready for operation again after being switched off
  • Easy to mount thanks to a status LED that indicates the optimal mounting position of the motor feedback system
  • Can be installed in almost any position by rotating the M12 male connector
  • Maintenance-free due to non-contact measurement principle, therefore no machine downtimes due to wear and tear
  • Simple integration of the system thanks to the HIPERFACE® or HIPERFACE DSL® interface
  • High availability compared to optical systems – even with dust, contamination and moisture
  • STL70-2 certified according to SIL2 and PL d (HIPERFACE® interface)


Ultra high speed measurement for linear direct drives

Precision, speed, dynamics, and high stiffness – it is exactly these properties that play a significant role in modern applications in drive technology. The STL/ETL70 motor feedback system fulfills all these properties with the help of the HIPERFACE® or HIPERFACE DSL® interface. The magnetic principle of operation, the long measuring length of up to 16 m, and the high resolution open up a broad range of application possibilities for absolute position detection. Integrated into the motor feedback system are the latest sensor and analysis technology. Thanks to HIPERFACE DSL®, the ETL70 is the world’s first linear motor feedback system with one cable technology.
