Product Description
Robust design

The rotor unit is screw-fastened or press-fitted for direct coupling. This rigid design permits high vibrational loads of up to 400 m/s² on the stator and 600 m/s² on the rotor. The robust inductive scanning method is also particularly resistant to contamination and magnetic fields.

Functional safety

Rotary encoders of this series are available with functional safety and a functionally 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.

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 or a version with external temperature sensor support.

Compact design

The rotary encoders of this series feature high ruggedness and reliability in a compact design. Their small footprint makes them ideal for tight installation spaces.
