Proximity switches can help monitor the position of objects on a production line and trigger specific actions or processes when an object is detected. These sensors are widely used in fields such as industrial automation, robotics, and safety systems. Most of the existing proximity switches are Figure 1 As shown, a magnetic field can be generated after the proximity switch is powered on. When an object approaches the magnetic field, it will cause a certain impact on the magnetic field.
