Netzer Electric Encoders
Motion Control Products Ltd is proud to introduce the advanced Electric Encoder™ range from Netzer, featuring world-patented digital encoder technology. These absolute-position rotary encoders deliver high-performance feedback solutions designed for the most demanding industrial and environmental applications.
High-end Absolute Position Encoders
Netzer encoders are available as standard “off-the-shelf” models or fully customised solutions to meet specific customer requirements. The Electric Encoder™ technology offers a unique contactless, hollow-shaft design, delivering unmatched precision, reliability, and compactness. This configuration ensures minimal axial space, low inertia, and lightweight construction, making it ideal for motion control systems where size and weight are critical.
Unlike traditional rotary encoders, Netzer’s solution utilises dynamic capacitance variations between two PCB plates – a passive rotor and a transceiver stator – for position detection. The system continuously scans the full 360° of the rotor’s circumference, generating a precise analogue output based on the sine and cosine components of its angular position. This innovative method ensures exceptional accuracy, robustness, and noise immunity.
