Robotic joint encoder

The absolute encoder uses the principle of capacitive sensing and signal modulation and demodulation to measure the position, instead of the photoelectric detection technology, to achieve more than high resolution and high accuracy. Because the sensing area of the detector is a 360-degree annular surface, the relative position accuracy requirements of the moving disk and the static disk are reduced. Mechanically, it has the characteristics of no bearing, large bore, and thin. Using unique technology for absolute position addressing, the encoder can output any angle value within one week after power on. From the perspective of application effects, the thickness and cost of the servo motor can be reduced. The superior characteristics of the large-bore hollow shaft are suitable for applications such as robots, CNC turntables, and direct-drive motors. The installation method, communication protocol, and electrical specifications of the encoder can be customized according to customer needs.
