Off-Axis configuration enhances the design flexibility

Rotation angle sensor, AK7455, for magnetic encoders can be designed with either Shaft-End or Off-Axis configuration. It is also available in the structure that a magnet cannot be attached to the end of shaft, such as a hollow motor for wiring cables.

For Shaft-End configuration, there are following concerns due to routing the cable outside.

• The movable area should be limited.
• Peripheral devices and cables may interfere.

For Off-Axis configuration, there are following advantages because the cable can be passed through the shaft.

• Wide movable area (360°) "
• Peripheral devices and cables are less likely to interfere.

With a magnetic encoder using the AK7455, it is possible to achieve an accuracy of about 0.1 ° even in Off-Axis configuration as well as Shaft-End by performing calibration.
