Q: Which connector should be selected for the hydraulic control system of shield tunneling machines?

A: The WS series aviation connectors (IP67) are recommended. They feature oil resistance (compliant with ISO 6743-4 standard) and 10g vibration resistance. With 8~16 pins, they can be adapted to signal transmission of hydraulic sensors (pressure and flow). Meanwhile, they adopt a threaded locking design (torque 1.0~1.5N·m) to prevent connector detachment during shield machine propulsion. The contact resistance is <5mΩ, ensuring control accuracy.
