Robust design
The blind hollow shaft allows the rotary encoder to be directly coupled to the mating shaft for optimal rigidity. What’s more, the inductive scanning principle is particularly tolerant of contamination and vibrational loads of up to 400 m/s² on the stator and 600 m/s² on the rotor.
Wide range of applications
For a wide variety of applications, this series offers the right encoder, including a multiturn version with a battery-buffered revolution counter for up to 65,536 revolutions and a version featuring external temperature sensor support.
Functional safety
Rotary encoders of this series are available with functional safety and a safe mechanical connection. Once integrated into an application with up to SIL 3 safety, they minimize malfunctions and facilitate the safe operation of machines and systems.
Compact design
The encoders of this series feature high ruggedness and reliability in a compact design. Their low profile makes them ideal for small installation spaces. Very high axial tolerances enable easy installation and smooth operation.
