Title:
MAGNETIC LINEAR POSITION DETECTOR
Document Type and Number:
WIPO Patent Application WO/2021/181534
Kind Code:
A1
Abstract:
This magnetic linear position detector (20) comprises a stator (1) and a movable element (2) that is capable of moving along a first direction in relation to the stator (1). One from among the stator (1) and the movable element (2) is provided with a magnetic detection element (3). The other from among the stator (1) and the movable element (2) is provided with a magnet (4) having a first surface (4a) that opposes the magnetic detection element (3). The first surface (4a) is magnetized such that the magnetization direction thereof changes in an arc shape centered around a magnetization center point (5). The output of the magnetic detection element (3) changes according to the magnetic field direction.
