Hall Effect Sensors
Optimize Your Sensor Performance with Adams Magnetic Expertise
What are Hall Effect Sensors?
Magnetic Hall Effect Sensors are popular for their versatility in sensing position, velocity and/or direction. Offering non-contact and wear-free operation, they are low maintenance, essentially ‘set it and forget it’ operation. They come in a wide variety of shapes, sizes and price points. They can be as large as your fingernail or as small as a grain of sand.
Measurement
Position
To measure position, one uses a pre-defined defined magnet that moves towards/away from the sensor. The sensor detects the strength of the magnetic field and infers the location of the magnet from that data
Rotational Position
To measure rotational position, an array of Hall Effect Sensors is used in conjunction with a diametrically oriented magnet. The magnetic field distribution in the array is used to calculate the rotational position of the magnet.
Velocity
To measure velocity, one can use the same array configuration used for rotational position. Alternatively, one can position the Hall Effect Sensor off-axis and measure the pulses as the object rotates.
