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.

Functional safety

Rotary encoders from 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.

Wide range of applications

For a wide variety of applications, this series offers the right encoder, including a multiturn version with up to 4096 revolutions, a version with a battery-buffered revolution counter for up to 65,536 revolutions, and external temperature sensor support.

Proven standard

The rotary encoders of this series offer high reliability and perfected technology in a highly robust design. For decades, large numbers of them have successfully proven themselves in industries round the world.
