WS Series IP67 Connector for Shield Machine Hydraulic Control

PC Series Circular Connector Types and Specifications

Selecting the Right Connector for Shield Tunneling Machine Hydraulic Controls

For hydraulic control systems in shield tunneling machines, the WS series aviation connectors (IP67) are a recommended choice. These connectors are engineered to meet the demanding conditions of tunnel boring operations, where reliability and signal integrity are critical.

Key Performance Characteristics

• Environmental Protection: Rated IP67 for dust-tight and temporary immersion protection, suitable for wet and dusty tunnel environments.
• Oil Resistance: Compliant with ISO 6743-4 standards, ensuring compatibility with hydraulic fluids used in the system.
• Vibration Resistance: Withstands up to 10g vibration, preventing connection failure during machine propulsion and operation.
• Contact Reliability: Contact resistance of less than 5mΩ supports accurate signal transmission for pressure and flow sensors.

Pin Configuration and Signal Adaptability

The WS series offers 8 to 16 pin configurations, providing flexibility to accommodate various hydraulic sensor signal requirements. This adaptability allows for integration with pressure transducers and flow meters, ensuring precise control feedback.

Secure Mating and Locking Mechanism

A threaded locking design with a specified torque of 1.0 to 1.5 N·m secures the connection, preventing accidental detachment caused by mechanical shock or vibration during shield machine advancement. This feature is essential for maintaining uninterrupted operation in high-vibration environments.

Application Considerations

When selecting a connector for this application, verify the specific pin count needed for your sensor array and confirm the cable diameter range matches your wiring. The IP67 rating applies when the connector is properly mated and locked; ensure the mating procedure is followed to maintain the seal integrity.
