Contactless angle position sensor for accurate 360 degree angular measurement
Test & Measurement
The ams AS5162, a contactless magnetic angle position sensor for accurate
angular measurement over a full turn of 360 degrees is now available from
Mouser stock. A sub range can be programmed to achieve the best resolution
for the application. It is a system-on-chip device, combining integrated
Hall elements, analog front end, digital signal processing and best in class
automotive protection features in a single device.
To measure the angle, only a simple two-pole magnet, rotating over the
centre of the chip, is required. The magnet may be placed above or below the
IC. The absolute angle measurement provides instant indication of the
magnet's angular position with a resolution of 0.022° = 16384 positions per
revolution. According to this resolution the adjustment of the application
specific mechanical positions are possible. The angular output data is
available over a 12 bit ratiometric analog output.
The AS5162 operates at a supply voltage of 5V and the supply and output pins
are protected against over-voltage up to +20V. In addition the supply pins
are protected against reverse polarity up to -20V.
