AS5132 High-Speed Magnetic Rotary Encoder IC ams OSRAM AS5132 High-Speed Magnetic Rotary Encoder IC is a contactless magnetic rotary encoder for accurate angular measurement over a full turn of 360°. It is a system-on-chip, combining integrated Hall elements, analog front-end, and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the chip is required.
