Steering wheel application for a clock-spring module
THE CHALLENGE

Dynamic Motion.
Reliable Connection.

The circuit needed to move continuously with the steering wheel while remaining secure inside the compact steering hub.

The design had to coil into a 3–4 inch diameter, provide snag-free movement and terminate into custom connectors without repeating the mechanical failures of the previous solution.

MOTION 3–4" Coiled Diameter
RELIABILITY Snag-Free Dynamic Flexing
TERMINATION Custom Connector Interfaces
THE PICA SOLUTION

Multiple Technologies.
One Drop-In Assembly.

PICA integrated FFC, rigid PCBs, custom connectors and molded housings into one complete solution designed for continuous movement inside the steering hub.

01

9' FFC Design

Long FFC provided the dynamic flexing required inside the hub.

02

Rigid PCB Integration

The FFC was terminated to rigid PCBs at each end.

03

Connector Transition

PCB-mounted pins transitioned signals to custom connectors.

04

Molded Housing

Injection-molded housings encapsulated the complete assembly.

~15,000/YEAR
No Known Warranty Claims

The drop-in assembly has delivered robust field performance since entering the market in January 2020.
