ams-OSRAM USA INC. AS5140H-ASSU

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
