The AS5140H-ASSU is a high-precision, contactless magnetic rotary encoder designed for accurate angular position sensing over a full 360° rotation. It utilizes Hall effect technology to detect the orientation of a diametrically magnetized magnet placed above the device. This sensor is robust, suitable for harsh environments, and ideal for automotive and industrial applications where durability and reliability are critical.
Features:
10-bit absolute angular position resolution (1024 positions per revolution)
Incremental output with 512 pulses per revolution (PPR)
PWM and Serial Synchronous Interface (SSI) outputs
Contactless magnetic sensing with no mechanical wear
User-programmable zero position
High rotational speed capability (up to 10,000 RPM)
Built-in diagnostic features for magnet detection and system integrity
Wide operating temperature range for automotive-grade reliability
Dual-supply voltage operation (3.3V and 5V)
Suitable for brushless DC motor commutation, rotary knobs, and encoder replacement
