ams AS5045 Rotary Sensor

描述

The AS5045 is a 12-bit rotary position sensor (previously known as encoder) for absolute angular measurement and with a PWM (=pulse width modulation) 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 12 bit = 4096 positions per revolution and it is provided as a digital value on the serial interface (SSI) and on the PWM 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.
