IC rotary encoder AM512B

absolutemagneticnon-contact

The IC senses the angular position of a permanent magnet placed above the chip. The permanent magnet must be diametrically polarized and of cylindrical shape. The AM512B uses Hall sensor technology to detect the magnetic flux density distribution at the surface of the silicon. Hall sensors are placed in a circular array around the center of the IC and deliver a voltage representation of magnetic field distribution. Features Contactless angular position encoding over 360° 9 bit absolute encoder High rotational speed up to 30,000 rpm 5 V power supply Low power consumption 20 mA typical. Extended operating temperature range (–40 °C to +125 °C) SMD package LQFP44 Benefits Ideal for harsh environments due to magnetic sensing Complete system-on-chip solution Factory optimized linearity RoHS compliant
