Inductive position encoder offers high accuracy at high rotation speeds
The RAIK060 is a complete solution for rotary position measurement in off-axis applications. Resistant to interference and contamination, this encoder is ideal for industrial motor applications and robots.
The RAIK060 from Vishay is an off-axis rotational absolute inductive kit (RAIK) encoder with a diameter of 60 mm which can measure rotary position accurately and precisely at rotation speeds up to 10,000 rpm. It is intended for use in demanding industrial applications, including in motor drives, robots and motion-control applications.Â
Accuracy of angle measurement is 0.01%, and the sensor resolves measurements to 18 bits, or 0.0014°. The RAIK060 provides its measurement outputs in BiSS-C, SSI, or SPI format. Latency is a maximum of 5 ”s.Â
The rotor is composed of multiple inductive traces printed on a PCB. The electrical fields are read by inductive cells mounted on the stator, which allows the absolute position of the rotor to be determined.Â
The value of the inductive sensing principle lies in its tolerance of operation in hostile environments, including exposure to interference from electromagnetic fields, to dust and liquids, and to high temperatures.
