Broadcom AEAT-9988M Magnetic Encoder ICs
Broadcom AEAT-9988M Magnetic Encoder ICs are precise 360° angular magnetic rotary sensors. The Broadcom AEAT-9988M ICs offer absolute and incremental signal outputs, making them suitable for various applications. The sensor integrates Hall elements with advanced analog and digital processing in a single device. A dual-track magnet rotating perpendicularly generates the required magnetic fields. Magnet ring sizes range from 20mm to 50mm in inner diameter.
