Our Clockspringcables

Clockspring cables are flexible electrical connections in the steering wheel that allow the airbags, horn and other controls to remain connected to the vehicle while the steering wheel is turning. These cables ensure a continuous electrical connection, even when the steering wheel is turning, and are crucial for the safety and functionality of modern vehicles.

Short band technology (Loop-back)

General information

Short cable technology uses a flat, spirally wound cable that winds and unwinds as the steering wheel turns. The flat cable forms movable loops with a defined diameter. This ensures that the connection remains intact at all times without the cable being overstretched or damaged. The technology ensures reliable signal transmission and increases the service life of the clockspring cable.

Structure and data

copper thickness	0.035 mm
Conductor width	Costumer-specific (0.45 mm- 20 mm)
Cable thickness	approx. 0.12 mm

Advantages

Cost efficiency: The combination of reduced material usage and higher reliability helps to reduce overall costs over the life cycle of the vehicle.
High reliability: The use of precision flat copper conductors of the highest quality results in excellent bending fatigue strength, which increases the reliability of the system.
Compact design: Short ribbon technology uses shorter and more compact cables that can be integrated into the Clockspring module to save space. This results in a smaller and lighter component overall, which is particularly important in the design of modern vehicles.

Long band technology

General informations

Long band technology is a variant of the technology used for clockspring cables (coil springs) in the automotive industry. Similar to short-band technology, it is used to ensure electrical connections between the steering wheel and the fixed vehicle electronics while the steering wheel is being turned. In addition, window technology can be used to make interruptions in the insulation in order to contact the cable at any point.

Structure and data

Copper thickness	0.125 mm
Conductor width	customer-specific (0.65 mm - 5mm)
Cable thickness	approx. 0.3-0.33 mm

Advantages

Extended freedom of movement: The long cable technology allows more turns of the steering wheel without the risk of overstretching the cable
Improved longevity: By distributing the tension evenly over a longer cable, the life of the coil spring and cable is increased.
Use in commercial vehicles: Long belt technology is often used in utility vehicles or vehicles with higher demands
