Operation Principle
The built-in position switch monitors the spool position. When the solenoid is energized and the spool shifts to the set stroke point, output A opens and output B closes. If the spool does not reach that point, the switch does not change state.
The switch signal goes to a PLC or industrial computer, which uses it to control or drive hydraulic components and other machine motions.

D. Statement of Connector and wiring
- VCC (18～24V DC), red wire.
- Output B, White wire.
- GND, Black wire.
- Output A, Blue wire.
- The shield wire connects to the housing.
- This switch is dedicated to stroke-point monitoring.
- When the trigger point is reached, output A (4 pin) non-conductive – normally closed.
- Output B (2 pin) conductive-normally opened.
- The switching point is adjusted by moving the outer tube on the inner tube or by the core thread, and is set at the factory before shipment.
Notes
- When the position switch drives an inductive load, such as a motor or relay coil, opening the load circuit produces a high induced voltage that may damage the switch or shorten the valve life. A surge protection device is recommended.
- Do not disassemble the valve body. Do not replace internal or external components. Do not replace or modify the internal throttle.
- The position switch can only be set and checked by the manufacturer.
- The hydraulic system must keep the spool free from shock and vibration.
- Do not drop the valve onto a hard surface from higher than 30 cm; the built-in sensor may fail.
- Keep the hydraulic oil clean; contamination shortens valve life or causes damage. Use filters with a filtration ratio of βx = 75 (x = 25 μm).
- Use ISO VG32 or ISO VG46 hydraulic oil, or water-glycol fluid.
