When subjected to a magnetic field it responds with an output voltage proportional to the magnetic field strength.
Driving industrial innovation with small size sensors.
Digital output hall effect sensors are primarily used in magnetic switch applications to provide a digital voltage output.
A hall effect sensor is a device that is used to measure the magnitude of a magnetic field.
When the magnetic flux density around the sensor exceeds a certain pre set threshold the sensor detects it and generates an output voltage called the hall voltage v h.
It is a continuous time ratiometric linear hall effect sensor optimized to accurately provide a voltage output that is proportional to an applied magnetic field.
Many automotive hall effect sensors have a built in internal npn transistor with an open collector and grounded emitter meaning that rather than a voltage being produced at the hall sensor signal output wire the transistor is turned on providing a circuit to ground through the signal output wire.
The output signal from a hall effect sensor is the function of magnetic field density around the device.
It has a quiescent output voltage that is 50 of the supply voltage and provides 2 5 mv g.
Frequently a hall sensor is combined with threshold detection so that it acts as and is called a.
Consider the diagram below.
