AS5410 Linear Position Sensor

14-bit Linear Absolute Position Sensor With Digital (Interface) and PWM Output

The AS5410 is an absolute position sensor for linear movements. To measure a long strocke (+/-25mm) with a large airgap (~10mm) a contactless magnetic sensor technology is used.To measure the absolute position of the motion a simple 2-pole magnet is required. The absolute information of the magnet position is measured with a 14-bit resolution and the digital value is provided via the serial interface (SPI) and PWM output signal.
