magneticmechanical18-bit

First Hollow Shaft Kit with a Battery-free Multiturn Battery-free Rotation Counter Based on Energy-Harvesting Technology Hollow Bearingless Center Design for Optimal Mechanical Layout on Robotic Joints and Drives Shafts 30 mm or 50 mm Internal Diameter Sizes Available Capacitive Measurement System Allows for High Accuracy Even in Harsh Environments Non-Proprietary Interfaces of SSI and BiSS C Standards Easy to install and requires no maintenance Battery-free Multiturn Counter – Energy-Harvesting Wiegand Sensor For multi-turn models, the rotation counter is self-powered, using POSITAL’s Wiegand energy-harvesting technology. This eliminates the need for backup batteries and lowers maintenance costs. No external power required – No batteries Longer lifespan Operates in harsh environments Non contact measurement – No mechanical wear Absolute Singleturn Position - Capacitive Measurement Technology Each encoder has two principle components, a stator and rotor, both containing specially shaped conductive surfaces. These surfaces, which function as capacitor plates, are positioned in close proximity. As the rotor turns, the patterns of the conductive surfaces change their relative position, causing changes to capacitive coupling in the system. This in turn causes changes to the amplitude and phase angle of a high-frequency electrical signal generated by exciter circuits in the stator. Special ASIC devices capture and decode these signal variations to determine the rotor’s angular position to a high level of precision.
