[0038] To further implement the above technical solution, two 3-pin M8 male connectors and one 6-pin M8 male connector are provided on the same side of the circuit board B. The two 3-pin M8 male connectors are connected to the magnetic sensor 10, and the one 6-pin M8 male connector is connected to the junction box 9.

[0039] To further implement the above technical solution, a pneumatic solenoid valve integrating a magnetic opening wire also includes a lower shell 4 for enclosing the first pilot head 2 and the second pilot head 3.

[0040] To further implement the above technical solution, a pneumatic solenoid valve integrating magnetic opening wiring is provided, which also includes a pilot head cover 7, arranged after the connecting circuit board B and fixed to the lower shell 4 of the pilot housing. The pilot head cover 7 has 3 M8 female connectors on its outer side, and each M8 female connector is connected to the M8 male connector of the connecting circuit board B. The junction box 9 and the magnetic sensor 10 are connected to the connecting circuit board B through the M8 female connectors.

[0050] After the action signal is sent from the junction box, the output level signal is transmitted to the solenoid valve through the connecting circuit board B and the connecting circuit board A. The first and second pilot heads are energized to control the piston inside the solenoid valve body to push the shaft core, thereby switching left and right, so that compressed air can enter each air pipe. The solenoid valve starts to work, which in turn drives the piston of the pneumatic actuator, such as the cylinder. The magnetic switch is used to detect the position or status of the pneumatic actuator and provide feedback. The magnetic switch signal changes, and the changed magnetic switch signal is transmitted to the junction box through the 3-pin interface of the connecting circuit board B and then through the 6-pin interface of the connecting circuit board B, realizing closed-loop control.
