High accuracy angle sensor for Shaft-End and Off-Axis configuration

High accuracy angle sensor for Shaft-End and Off-Axis configuration

ES

Description

The AK7455 has a disturbance magnetic field (magnetic field noise) correction function that conventional magnetic sensors cannot support. Angular errors due to disturbance magnetic fields can be reduced, and this function can be used to reduce fluctuations in temperature characteristics. In addition, the degree of freedom of the through-axis arrangement (Off-Axis) is further increased, and the sensor position in the motor system can be increased. You can consider flexibly.

Key Features

  • Angle error correction function It has an angle error correction function and can detect angles with high accuracy.
  • Off-Axis placement support In addition to the shaft end (Shaft-End) arrangement, it corresponds to the Off-Axis arrangement where ICs are arranged next to the two-pole magnetized magnet, so that a through-axis motor system can be configured. As a result, the motor system can be made thinner and hollow.

Applications

  •                                 Compact absolute rotary encoder, Compact input device (mode selector, control volume)  Substitute for potentiometer, Rotary switch
