Three magnet-free inductive place sensors from Renesas present a cheap various to magnetic and optical encoders. With completely different coil architectures, the ICs handle a variety of functions in robotics, medical units, good buildings, residence home equipment, and motor management.
The twin-coil RAA2P3226 makes use of a Vernier structure to ship as much as 19-bit decision and 0.01° absolute accuracy, offering true power-on place suggestions for precision robotic joints. The one-coil RAA2P3200 prioritizes high-speed, low-latency operation for motor commutation in e-bikes and cobots, with built-in safety for sturdy industrial use. Additionally utilizing single-coil sensing, the RAA2P4200 provides a compact, cost-efficient choice for low-speed functions similar to service robots, energy instruments, and medical units.
All three sensors share a typical inductive sensing core that allows correct, contactless place measurement in harsh industrial environments. Every system helps rotary on-axis, off-axis, arc, and linear configurations, and consists of automated achieve management to compensate for air-gap variations. A 16-point linearization function enhances accuracy.
The sensors are actually in quantity manufacturing, supported by a web-based design device that automates coil structure, simulation, and tuning.
The submit Inductive sensors broaden motion-control choices appeared first on EDN.
