The crank shaft actuator is used to power a vehicle trunk. The actuator operation is smooth and offers a very low noise level compared to conventional power closure solutions. The best-in-class acoustic absorption quality is achieved through innovative kinematics reducing the noise modulations. The system intrusion on the car body is limited, which eases post-equipment. The assembly on the vehicle is easy through clipping on standard ball joints. It can be delivered with incremental or absolute sensor, depending on customer's requirements.
