Magnetic switch is a high-sensitivity position detection component based on the principle of magnetic induction. It is mainly used to sense the real-time position of a cylinder piston and output electrical signals for precise automated control. The product is widely applied in pneumatic and hydraulic systems, automated production lines, and various industrial control scenarios. Featuring a compact design and fast response, it is an ideal solution for position feedback and process control in industrial automation.

How it works

  • Magnet in piston — the moving trigger source
  • Slot on profile tube — where the switch clips on
  • Non-contact sensing — zero mechanical wear, long life
  • Clean signal output — NPN/PNP to PLC or controller
