Magnetic sensors respond to the external magnetic field. They are characterized by great sensitivity even in very small design (we produce from a diameter of 6.5mm).
They can be divided into two basic groups according to the sensing element on the reed contact and the Hall element.
Sensors with reed switch are two contacts sealed in a housing that are connected by magnetic field.
Contacts are characterized by a wide range of applications with great reliability.
In some applications, it is necessary to add damage protection to the circuit to ensure the required reliability.
We produce in three basic designs:
Normal open NO
Normal close - NC
Switching - NO / NC
Sensors with Hall Sensor are semiconductor devices that use Hall effect.
We produce the sensors as a complete system including protection, for example against polarity reversal.
Sensitivity is given in mT (millites) or G (gauss), the lower the value, the more sensitive the sensor is. (1 G (gauss) = 0.1 mT (millites)
These sensors can be further divided into:
Unipolar
Responding to one pole, which can be used for specific applications, or to observe the polarity of the magnet being scanned.
By default, it scans the south pole, and can be customized to scan the north pole of the magnet.
Omnipolar
If it does not require an application, it is not necessary to distinguish the northern and southern poles.
The internal arrangement is like a pair of unipolar sensors, one of which scans the north and the second south pole.
This can be used to switch high frequencies when changing the polarity of the magnet.
We produce in designs:
PNP
NPN
Normal open - NO
Normal close - NC
Switching - NO / NC
