Magnetic sensor - Many applications in electronics and robotics
The magnetic sensor available in this category mostly bases its operation on the use of a reed switch hidden under the housing. A reed switch is a circuit element that closes and opens upon close contact with an object having a magnetic field. Such a device has contacts covered with a thin layer of very conductive material (e.g. tungsten or gold), which is selected depending on the specific purpose. Reed switches are divided into two types. Less popular - remanent - are those that, under the influence of a magnetic field, change their state to the opposite one, but after moving away the object emitting the magnetic field, the state remains the same (without introducing any force or energy into the system). Subsequent contact with a magnetic field of opposite polarity will cause a change in state. Non-remanence reed switches are much more often used - they operate by maintaining one of the states only during close contact with an object emitting a magnetic field. State changes involve closing and opening the circuit - for example, after removing the magnet from near the reed switch, the circuit will be interrupted (opening the window). Information about such an event may be registered in the connected microcontroller, which will react to it, for example by activating an alarm signal. Every reed relay - electromagnetic - works in a similar way.
What will you find in our offer?
We offer many variants of practical use of reed switches. The most popular is a magnetic sensor that controls the closing or opening of windows or doors. Based on the example described above, it can act as an alarm switch. Liquid level sensors, additionally equipped with a float, which also use a magnetic sensor, are also very useful in industry. The Hall sensor is an element that also uses close contact with a magnetic field - the device uses the Hall effect. Thanks to it, you can easily measure, for example, the number of revolutions made by the engine by attaching a small magnet to the engine shaft. Such sensors are commonly used in everyday devices, but they are also irreplaceable in industry. You can also purchase individual reed contacts from us and use them for your own project.
Magnetic sensors - FAQ
A magnetic sensor is an electronic component that detects changes in the magnetic field. They are used, for example, as part of door and window opening sensors in alarm systems .
Magnetic field sensors use the operation of reed switches. As a result of changes in the magnetic field, the reed switch changes its state, which closes or opens the electric circuit and results in a change in the signal received from the sensor. You can learn more about the operation of reed switches in our article " Reed switch - what is it for and how does it work? ".
The easiest way to check a magnetic sensor is to use a resistance meter .
A Hall effect sensor (Hall sensor) is an electronic component that measures the magnetic field strength and current , using the Hall effect (the relationship between the presence of a magnetic field and the flow of electricity through conductors).
