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.<\/p>\n<div class=\"row\"  id=\"row-783177924\">\n\n\t<div
