Potentiometric encoders

Our potentiometric encoders provide a reliable method for measuring angular displacement. They operate on the proven potentiometer principle: mechanical rotational movement is converted into Voltage proportional Voltage the wiper and immediately output. As a result, they deliver a real-time signal without any sampling, conversion, or processing delays—making them ideal for fast control loops and dynamic processes.

Their simple design allows for effortless integration into existing systems, making them highly functional and reliable in a wide range of applications. In addition, we develop and manufacture our own conductive plastic compounds for potentiometers in-house. These conductive resistive elements are based on a proprietary formula and are optimized for low wear, very low contact resistance to ensure excellent contact throughout their entire service life, and minimal drift over temperature and service life.

Thanks to their cost-effectiveness and durability, they offer invaluable advantages even in industrial machinery, where they ensure continuous process monitoring at minimal maintenance costs. Their strengths are particularly evident in applications that require continuous monitoring.

Key advantages of potentiometric encoders

• Simple design: The simple design and low power consumption reduce potential sources of error, increase reliability, and minimize maintenance requirements.
• Durability: The high-performance compounds used in the resistive elements ensure minimal wear and low drift, thereby guaranteeing long-term, stable performance in a wide variety of environments.

Typical applications for potentiometric rotary encoders

• Industrial machinery: Effective process monitoring with reduced maintenance requirements while maintaining consistent performance.
• Automation systems: Enable reliable monitoring of linear and rotary movements to ensure safe operation in demanding applications.
• Control and proportional valves: As position sensors with very low power consumption, they provide high-resolution, repeatable feedback on the valve position, thereby enabling precise metering of process fluids or gases—ideal for energy-efficient, sensitive control loops.
