ams – AS5600: Easy-to-Use Magnetic Position Sensor Offers Durable, Contactless Replacement for Potentiometers

ams_November2014_pg10ams-logo
The AS5600 is an easy to program magnetic rotary position sensor with a high resolution 12-bit analog or PWM output.

This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. This AS5600 is designed for contactless potentiometer applications and its robust design eliminates the influence of any homogenous external stray magnetic fields.

The industry standard I²C interface supports simple user programming of non-volatile parameters without requiring a dedicated programmer. An easy start and stop position programming in a so called “3 wire mode” without a programmer or digital interface is also implemented. The default range of the output is 0° to 360°. The AS5600 can be applied to smaller range by programming a zero angle (start position) and a maximum angle (stop position). The AS5600 is also equipped with a smart low power mode feature to automatically reduce the power consumption.
