Wheel Speed Sensor Wiring Harness Injection Mold

Core Advantages

• Integrated Molding & Assembly Capability: Leveraging over 15 years of plastic mold experience, we simultaneously develop connector housing molds and assembly processes, ensuring consistent connector dimensional accuracy and terminal retention force.
• Signal Transmission Stability: Designed with twisted pairs or shielding structures to effectively suppress Electromagnetic Interference (EMI), ensuring signal integrity for lowlevel wheel speed sensor signals.
• Harsh Environment Tolerance: Materials selected for wire and connectors operate reliably across a wide temperature range (40°C to +125°C). Seal design achieves IP67 or higher protection ratings against water, oil, and salt spray corrosion.
• Mechanical Strength Assurance: Connector housings are injection molded from reinforced engineering plastics, featuring robust secondary locks (TPA) or integrated locking mechanisms to prevent terminal pullout due to vehicle vibration.

Product Features

• Precision Connector Molding: Connector housings are molded using highprecision tools, with mating interface dimensional tolerances controlled within ±0.05mm to ensure reliable mating with sensors and ECUs.
• Terminal Crimping & Retention: Automated crimping equipment strictly controls crimp height and pull force. Terminal retention force within connectors meets USCAR2 or customerspecific specifications.
• Sealing Structure Design: Integrates radial or face seals, typically made of silicone or EPDM, to prevent moisture and contaminant ingress.
• Harness Fixing & Protection: Wires are wrapped with abrasionresistant tape or corrugated tubes; rubber grommets are applied at critical bending points to resist stone impact and longterm flex fatigue.
• Environmental Compliance: Wire insulation and connector materials comply with RoHS, REACH, and other environmental regulations.

Applications

This product is widely used for wheel speed detection in various passenger and commercial vehicles. It primarily connects active or passive wheel speed sensors to ABS/ESC control modules, suitable for both traditional fuel vehicles and new energy vehicles.

Common Issues & Solutions

• Issue: Signal noise or interruption during transmission.
  Solution: Check shield grounding continuity; optimize wire twist pitch for better EMI immunity; ensure contact resistance between terminals and sensor/ECU pins is below specified limits.
• Issue: Connector disengagement due to vehicle vibration.
  Solution: Incorporate TPA (Terminal Position Assurance) or CPA (Connector Position Assurance) features in the connector design; inspect the molding integrity of terminal locking latches.
• Issue: Harness conduit hardening or cracking at low temperatures.
  Solution: Select conduit materials rated for low temperatures (e.g., 40°C); optimize conduit wall thickness to reduce stress concentration points.

Important Considerations

• Route the harness away from high heat sources (e.g., exhaust pipes) and moving parts; ensure fixing clips are spaced appropriately to prevent harness sagging and vibration.
• When installing the connector, ensure an audible "click" is heard from the locking mechanism and gently pull back to confirm secure mating.
• Regularly inspect the harness outer sheath for wear, especially at points passing through sharp body edges or holes.
