As the name indicates, magnetic speed sensors detect speed in a variety of circumstances involving
targets such as ferrous metal objects (for example, blades, shafts, and gears) and magnets. These targets
interrupt a magnetic field as they pass by the sensor, which converts that action into data on target
speed. Companies such as Sensor Solutions specialize in supplying sensors designed for magnetic field
detection, and the applications are numerous.
These magnetic devices have existed for some time now and have proven themselves to be a reliable
solution for speed detection. They are versatile as well, coming in a wide range of shapes and
configurations. Depending on your needs, you can use a stock sensor or have one custom built to your
exact specifications.

A common category is the variable reluctance sensor, which is passive in nature (that is, does not
require an external power source). Seeing increasingly more use is the active or amplified sensor, which
uses electronics to convert analog signals to digital output. Other types of speed sensors include the Hall
effect zero sensor and the RF sensor.
If you are in a position to need a speed sensor, a number of factors are involved in making a selection.
You might have your own preference based on experience, but application parameters can also dictate
the choice. Do you need an analog or digital signal? What are the target’s shape, size, and material?
What kind of environmental conditions are you dealing with? For example, will the sensor be subject to
extreme and/or fluctuating temperatures or heavy shock and vibration? These factors should figure into
the decision you make.
Most people do not have occupations requiring this level of intimacy with magnetic sensors. However,
these devices are everywhere. For instance, speed sensors are found throughout automobile
powertrains. They are also in office equipment and ordinary household appliances such as laundry
machines. Typically out of sight, these small gizmos perform their important tasks countless times a day
to keep ordinary things running smoothly.
