Hall Switches

Overview Hall Switch Families

The simplest application is to use the sensor as a “digital switch”. The magnetic field strength is measured and compared with a fixed threshold level predefined or programmable in the sensor. As soon as this value is exceeded (switching point) the switching state at the output of the sensor changes and the output transistor is switched on or off. Two types of switches are available. 3-wire version with an open-drain output or 2-wire versions with current-coded output.
