Trailer Handshake Connector (Red) – Dual-Channel Pneumatic-Electrical Interface for Semi-Trailer Emergency Braking

Description

The red Trailer Handshake Connector (Part No. 9522010020) is a dedicated dual-channel pneumatic-electrical interface for semi-trailer emergency and parking brakes, compliant with ISO 7638-2 and SAE J3068. It integrates a ​7-pin electrical connector (with dedicated ABS/EBS channels) and ​dual pneumatic ports (primary + emergency circuits). Featuring ​glass-fiber reinforced nylon housing (UL94 V2 flame-retardant) and ​silver-plated copper contacts (≤3mΩ resistance) with ​FKM seals (-50℃~200℃), it ensures zero-delay emergency braking activation under high load and vibration.

Core Functions:

1. ​Emergency Activation: Red color codes emergency braking, triggering ABS/EBS via dual pneumatic (1.0~1.5MPa) and electrical paths.
2. ​Redundancy: Backup circuit auto-switches if primary fails.
3. ​Signal Integrity: Shielded ABS lines (2.5mm² twisted pair) isolate from power lines (6mm²).

Key Importance:

• ​Safety Critical: Final safeguard against brake failure.
• ​Material Impact:
  • ​Silver Plating: Reduces arcing and enhances signal stability.
  • ​FKM Seals: Resist brake fluid and high-pressure washing.
  • ​Structural Strength: ECE R55-certified housing withstands 50MPa pressure.

Replacement Guidelines:

1. ​Color Compliance: Red connectors are emergency-only; never mix with yellow/blue.
2. ​Pneumatic Sync Test: Post-installation pressure differential ≤0.05MPa.
3. ​Protocol Calibration: Match ABS/EBS protocols via diagnostic tools.
4. ​Dust Cap: Install IP67 cap to prevent short circuits.
