SP119 Soway Aluminum Magnetic Proximity Sensor For Truck/Door
Magnetic proximity switch is the general term of sensors， which replaces limit switch and other contact detection methods and aims at conducting detection without contact with the detection object. It can detect the move and existence information of the object and transform them into electrical signals. The sensor products which can also detect the presence and proximity of objects without any physical contact are called “proximity switch”. There are different types of proximity switch, such as magnetic induction, electrostatic capacity, ultrasonic, photoelectric, Hall and so on. It is widely used in the position alarm of automobile, intelligent home, safety protection and industrial control area.
