The entire assembly is housed within a frame or housing, which provides structural support and protects the internal components from damage. The housing also typically includes mounting features for attaching the actuator to the application. Limit switches may be included to prevent over-travel and protect the actuator from damage at the end of its stroke. These components collectively ensure precise and controlled linear motion.
