Achieved a maximum resolution of 23 bits with a magnetic encoder using dual-track magnets, featuring an integrated battery backup multi-turn counter function.
The 『AEAT-9988M』 is a magnetic rotary angle sensor that achieves high-precision angle measurement over a full 360 degrees of rotation. The dual-track magnet generates the necessary magnetic field by rotating in the vertical direction. The size of the magnet ring can be widely selected from an inner diameter of 20mm to 50mm. With the absolute angle measurement function, the angle position of the magnet can be instantly grasped, and the resolution can be selected and reset between 16 bits and 23 bits.
