Absolute rotary encoders

The new reference in compact, high-precision non-contact encoders by NETZER PRECISION

Netzer Precision’s compact absolute capacitive encoders represent a significant technological leap in the field of angular position sensing. Based on the company’s patented Electric Encoder™ technology, these sensors utilize spatially and temporally modulated electric fields to determine the absolute position over a full 360° range with outstanding precision.

This contactless architecture eliminates mechanical components prone to wear such as glass discs or light sources resulting in superior reliability and an extended operational lifespan. Their ultra-slim and lightweight design (less than 10 mm thick, with some models weighing under 15 grams) enables seamless integration into applications where space and weight constraints are critical.

Additionally, their hollow shaft design offers installation flexibility, making it easy to route cables or integrate additional mechanical components. Netzer encoders deliver high resolution up to 23 bits and exceptional accuracy, along with impressive immunity to EMI, RFI, and magnetic interference, making them ideal for the most demanding industrial and aerospace environments.

Typical applications include robotic arm positioning, gyro-stabilized platforms for surveillance systems and laser pointers, aerospace equipment, precision medical devices, and defense systems. Netzer Precision encoders combine compactness, accuracy, and durability to meet the expectations of the most challenging industries.
