Pursuit of eliminating factors that degrade accuracy: Rotating magnetic absolute encoder & high-precision multipole magnetic scale.
In April 2017, Midori Measurement released the first magnetic encoder developed in-house. The CE36M is a magnetic absolute encoder that pursues precision, achieving a resolution of 13 bits per revolution with an accuracy of 11 bits! It has excellent environmental resistance, with a structure that can withstand vibration, shock, and sealing. It covers a wide operating temperature range and is resistant to electromagnetic waves and external magnetic fields, making it suitable for industrial robots and medical devices. The magnetic scale for magnetic rotary encoders can utilize signals combined with magnetic conversion elements like MR sensors in the encoder. We provide high-precision, multi-pole magnetic scales tailored to user needs. For more details, please download the catalog or contact us. We plan to release the second in-house developed product within the fiscal year 2017 and the third in 2018.
