Renesas Electronics Corporation introduced a new family of magnet-free inductive position sensor (IPS) ICs that can be fully customized for various coil designs compatible with a wide range of industrial applications such as robotics, medical and healthcare, smart buildings, home appliances and motor commutation. Built for high resolution, precision, and robust performance, the new RAA2P3226, RAA2P3200, and RAA2P4200 sensor ICs offer a cost-effective alternative to traditional magnetic and optical encoders, which can be bulky, expensive, and require frequent maintenance. Renesas also launched a web-based design tool that allows customers to easily create custom sensing elements to meet their specific system needs.
Their durability and low upkeep make them a reliable and cost-effective sensing solution for motor drives, actuators, valves, service robots and infrastructure applications, where reliability and long-term performance are critical. All three products offer high precision in detecting target positions, with accuracy better than 0.1% of the full-scale electrical range. The RAA2P4200 targets low-speed applications such as medical devices and power tools and the RAA2P3200 is optimized for high-speed motor commutation.
In addition to these three products, Renesas will also introduce automotive-grade IPS, RAA2P452x and RAA2P4500, which will be available later this year. This automotive-grade solution offers a cost-effective option for low-speed body control and chassis systems without compromising quality.
