What Is The Difference Between The PNP And NPN Outputs Of The Hall Switch?
With the rapid development of science and technology, the application of Hall switches is more and more extensive. Hall elements refer to the output of trigger signals according to the magnetic field.
Hall switches often have NPN and PNP outputs, and many people confuse the two output concepts. Now let's explain the two differences in detail.
1. NPN (Normally Open) means that when the Hall sensor has no magnetic field, it outputs a low level, and when there is a magnetic field, it outputs a high level. NPN (normally closed) means that the Hall switch sensor outputs a high level when there is no magnetic field, and outputs a low level when there is a magnetic field.
2. PNP (normally open). When the Hall switch sensor has no magnetic field, it outputs a high level. When there is a magnetic field, it outputs a low level. PNP (normally closed), the Hall switch sensor outputs a low level when there is no magnetic field, and outputs a high level when there is a magnetic field.
The Hall switch is a non-contact switch with no delay, jitter, long life, and high performance.
Several characteristics of the Hall switch:
1. high response frequency
2. repeated positioning accuracy is high
3. the output waveform is pure, stable performance
4. with working status indicator
5. stable, can work reliably in the harsh environment of oil, dust, vibration, and temperature difference
6. a variety of output methods
7. Long service life and low cost.

Do You Know Magnetic Switch?
As a Magnetic Switch China Supplier, share with you. An electromagnetic switch is a switch controlled by an electromagnet, which is a combination of an electromagnet and a switch. When the electromagnet coil is energized, electromagnetic attraction is generated, and the movable iron core pushes or pulls the switch contact to close, thereby connecting the controlled circuit. Electromagnetic switches have a wide range of applications in various industries, and the most common is the contactor in the industrial field.
What is the Connection Method of the Hall Current Sensor?
Hall current sensors and voltage sensors only need to be connected to a positive and negative DC power supply. The measured current bus generally passes through the sensor or is connected to the primary side terminal, and then some simple connections are made on the secondary side to complete the main control circuit. Isolation detection, circuit design is very simple.

Do You Know the Application of Hall Devices in Resolution?
As a Bipolar Hall IC China Factory, share with you. An exceptional instance of an application that makes use of discrete position sensing is an auto shift selector. In change selectors there are commonly as few as 5 discrete settings (Park, Reverse, Neutral, Drive as well as Low). With a unipolar switch placed at each individual setting (P, R, N, D, and also L), each switch just switches on when the magnet in the shifter is relocated straight adjacent to the switch.
