Recently, Weishi Technology announced the launch of a new high-precision position sensor based on induction technology, RAIK060, which is suitable for industrial and other applications with strict requirements. Compared with magnetic technology-based solutions, the Vishay MCB RAIK060 absolute encoder kit has a thinner thickness of 5 mm, lighter weight of 15.5 g, higher speed of up to 10000 rpm, and shorter delay time of ≤ 5 μ s. In addition, the device is not sensitive to the magnetic environment, so it can be used near the motor.
The recently released position sensor is highly suitable for industrial applications such as robots, motor-driven systems, and others that require precise positioning, including conveyor belt control and automated guided vehicles. Its design variants can be dedicated to brake position control for unmanned aerial vehicles, commercial aircraft, regional aircraft, and eVTOL aircraft. In addition, RAIK060 can also provide pitch and yaw position control for windmills; Provide roller position control for cleaning robots; Provide brake position control for communication antennas, medical X-ray machines, and hospital beds.
For these applications, RAIK060 achieves>13 bit accuracy, 18 bit resolution, and ³ 17 bit repeatability, while maintaining resistance to external magnetic fields, moisture, air pollution, vibration, mechanical shock, and temperature changes. This position sensor adopts an off-axis design suitable for hollow shaft installation, with an effective electrical angle of 360 ° and a wide temperature range of -40 ° C to+105 ° C. The device has an outer diameter of 60 mm and an inner diameter of 25 mm, and can provide variable number of turns and SPI, SSI, or Biss-C output signals. The embedded self calibration of RAIK060 simplifies setup without the need for external software, and its air gap tolerance is ± 0.2 mm. Its frame includes LED status indicators for easy installation and assembly. For ease of use, the device can remember the last position before power failure, and the built-in self-monitoring function improves safety.
