ams AS5043 Rotary Sensor

Description

The AS5043 is a 10-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with a programmable analog output over a full turn of 360° based on contactless magnetic sensor technology. This device fits perfectly for on-axis applications where a simple 2-pole magnet rotates above or below the sensor IC and the zero position can be programmed into the device.The absolute magnet angular position is measured with a resolution of 10 bit = 1024 positions per revolution and it is provided as a digital value on the serial interface (SSI) and on the analog output signal.

With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.
