Abstract

A magnetic proximity sensor includes a normal magnetic field vector sensing element oriented to detect the magnetic field strength of a target magnet in a normal field vector direction. The magnetic proximity sensor also includes a transverse magnetic field vector sensing element oriented to detect the magnetic field strength of the target magnet in a transverse field vector direction. A logic circuit is connected to the normal magnetic field vector sensing element and to the transverse magnetic field vector sensing element, and is configured to indicate when both the magnetic field strength of the target magnet in the normal field vector direction is greater than a normal magnetic field vector sensing threshold and the magnetic field strength of the target magnet in the one or more transverse field vector directions is lesser than an absolute transverse magnetic field vector sensing threshold.
