This ceramic magnet ring is a radial ferrite ring magnet for motor magnetic rotary encoder sensors.
The appearance of ferrite ring magnet is smooth and flawless, with high dimensional accuracy, good consistency, subsequent processing, stable performance, shock resistance, and complex products. It is an indispensable signal source and constant magnetic source for micro-motor and automation industries. No other magnet can replace and match the sex.
The magnetization method of the permanent magnet can be single magnetization in the axial direction, multi-stage magnetization in the radial direction, or compound magnetization in the axial and radial directions.
