High-quality Clock Spring OEM LR043720 Car Airbag Coil for LAND ROVER

OE number: LR043720

Applicable vehicle type: Land Rover

The automotive clock spring, also known as a spiral cable or steering wheel spiral coil, is an essential electrical rotary connector located beneath the car's steering wheel, connecting the electrical components on the steering wheel to the vehicle's wiring harness. Its core consists of a precisely wound flat cable coiled within a spool, ensuring continuous electrical connectivity even when the steering wheel is rotated multiple times to the left or right.

Core functions and importance:

• Airbag signal transmission (core function): As the only dynamic pathway for the driver's airbag (DAB), it is responsible for reliably transmitting the ignition signal from the vehicle's ECU to the airbag. Its reliability directly relates to life safety.
• Multi-function steering wheel signal transmission: Transmits electrical signals for all buttons on the steering wheel, including audio control, cruise control, Bluetooth phone, gear shift paddles, etc.
• Horn circuit connection: Provides the current circuit for the horn button.
• Other extended functions: Some high-end models also integrate the connection function for the steering wheel heating coil.

High reliability design: The cables and internal structure have undergone tens of thousands of rotational fatigue tests to ensure a lifespan equal to that of the vehicle.

Ultra-high manufacturing precision: The mechanical structure of the drum and the length of the cable are precisely calculated to ensure a rotation range that covers the maximum total number of turns of the vehicle's steering wheel.
