Quantum Devices, Inc.
Quantum Devices designs and manufactures incremental optical rotary encoders and silicon photodiodes at its vertically integrated Wisconsin facility. Its encoders provide angle, position, and speed feedback for motion control, with optical incremental resolutions up to 20,000 pulses per revolution, sine/cosine outputs, and commutation capability for servo motor control. The company markets these encoders specifically for robotics, AGV/AMR, and servo-motor applications as precision motion-feedback sensors. Products are supplied to OEMs as robot supply-chain sensing components.
