Design Rotation Detection with Greater Freedom for Automotive Motors

The S-57W1/W2 S Series integrates a Hall element capable of detecting magnetic flux density in two different directions on a single chip, allowing it to automatically detect magnetic flux density with a 90° phase difference. The S-57W1/W2 S Series offers a high-sensitivity product with 0.8mT (typ.), enabling reliable detection of weak magnetic flux density. This makes it ideal for motor applications using multi-pole ring magnets with a large number of poles.
