Abstract

A linear actuator () in which a squeeze protection device is arranged, where the device is located in connection with the rear fixture () on the motor (). The squeeze protection device is based on a piezo element (), which as a module () is built into the actuator (), so that it is passed through by the forces, exerted by the actuator (). The piezo element () is equipped with cables (), which are connected to a printed circuit board () in the actuator (), where the connections for the actuator () are collected, so that the signal from the squeeze protection in an easy manner may be communicated to a control device (), which can stop the motor () or briefly reverse the direction of the movement and thus release a trapped object.
