Magnetic Sensors – An Introduction

Magnetic sensors, powered by reed switches, represent the perfect blend of simplicity and advanced functionality, making them essential across industries. Designed to detect changes in magnetic fields with precision, these sensors enhance automation processes through their reliable performance.

By incorporating added features—such as higher shock and vibration tolerance and extended sensing ranges—magnetic sensors offer more than just basic detection. They are commonly utilized in applications requiring high-speed sensing, such as automotive systems, industrial machinery, and home security setups.

What are Magnetic Sensors?

What are Magnetic Sensors? Reed switches offer a blend of simplicity and efficiency, making them indispensable in multiple sectors. Magnetic sensors use an inbuilt reed switch with additional features such as higher shock and vibration limits or added ON and OFF distance sensing to detecting changes in magnetic fields for accurate measurements and control, significantly enhancing industrial automation processes.

How do Magnetic Sensors Work?
When a magnetic field is present, the ferromagnetic blades inside the reed switch take on opposite polarities of the external magnetic field and attract each other, closing the circuit. This simple yet effective mechanism is utilized in home security systems, automotive applications, and various industrial uses for consistent and reliable performance.

Why Use Magnetic Sensors?
These sensors are pivotal in applications like belt speed and control, high-speed welding sensing, and end position sensing in pick-and-place arms. They offer enhanced efficiency, high speed sensing, safety and precision in industrial processes. Since they are hermetically sealed, they are safe to used even in explosive environments.

The integration of magnetic sensors in industrial automation brings substantial benefits, driving efficiency and innovation.
