Proximity switch, method for configuring proximity switch and proximity switch device

摘要

Between the branches of a U-shaped permanent magnet with longitudinal magnetization, the non-magnetic region in which the sensor is placed is formed by three identical poles. When the flat ferromagnetic triggering portion is drawn close to the two poles of the branch of the U-shaped magnet in plane parallel to the base of the U-shaped magnet, the switch signal triggered from the sensor by removal of the non-magnetic region can be evaluated.
