proximity sensor generate a magnetic field around the sensor through changes in the position and polarity of the trigger, causing the sensor's contacts to act. adopting a sealed design with a lifespan of at least 1 million times, it is easy to install and can be adjusted according to different application environments of customers. magnetic proximity switches, magnetic switches, magnetic sensors, and position switches are a general term for sensors that replace contact detection methods such as limit switches and are designed to detect objects without the need for contact. it can detect the movement and presence information of objects and convert them into electrical signals.it can also detect the proximity of objects and the presence of nearby detection objects in a non-contact manner in sensors are collectively referred to as "proximity switches", which are composed of magnetic induction type, electrostatic capacity type, ultrasonic type, photoelectric type, hall type, etc.
