EZA25PM Multiturn Encoder

The compact, contactless multiturn rotary encoder EZA25PM retains absolute position information for up to 40 revolutions, even when moved during power loss.

Its gearless and battery-free design enables maintenance-free operation, eliminates the need for rehoming after power loss and provides high reliability with long service life.

The encoder retains absolute position information for up to 40 revolutions, even during power loss. This true power-on capability eliminates the need for batteries and mechanical gear mechanisms, enabling maintenance-free operation, reduced system complexity and improved long-term reliability. In addition, rehoming procedures after unexpected power loss are no longer required.

Its contactless sensing principle minimizes mechanical wear and delivers stable, high-precision position feedback throughout the entire product lifetime. The EZA25PM features a field-programmable analogue output due to integrated teach-in functionality, allowing the output signal to be adapted directly to the mechanical limits of the application — even after installation.

The compact and proven Ø25 mm housing — likely making the EZA25PM one of the most compact true power-on multiturn encoders currently available — enables easy integration into space-constrained applications, while the modular platform architecture supports flexible customization for customer-specific requirements. Designed and manufactured in Germany, the EZA25PM combines advanced sensor technology with industrial robustness and long-term operational stability, making it ideal for automation, robotics, medical technology and other demanding motion control applications.
