Renesas IPS2200 inductive position sensor

Renesas Electronics has introduced the magnet-free IPS2200 inductive position sensor. Featuring high speed, total stray field immunity and efficient motor integration in a thin and lightweight form factor, the product is useful as an absolute position sensor in a wide range of industrial, medical and robot applications. It allows users to tailor sensor design for their applications and maximise the performance of the sensor’s accuracy.

The device is designed around the motor, allowing users to match the number of sectors to pole pairs of the motor and accommodating both off-axis (through shaft and side shaft) and on-axis positioning. The magnet-free sensor is up to 10 times thinner and 100 times lighter with up to 250 krpm electrical speeds compared with traditional resolvers.

The sensor’s thin and light form factor and total stray field immunity should enable easier motor integration and provide the standard materials required for users to manufacture their own resolver replacement, reducing bill of materials costs. With its 4- or 6-wire operation, it is said to provide up to 10 times faster speeds and low latency compared with resolver- or magnetic-based solutions.
