Actuators convert electrical energy into mechanical movement. Generally speaking, they can be divided into two main categories: pull/push DC solenoids and proportional DC actuators. While the former provides binary push or pull action, the latter can proportionally control movement of a connected load.
- Pull/push DC solenoids are mostly used for continuous pull- and push action in the most severe environments. They are typically used for engine shutdown, throttles, chokes, valves, clutches and other mobile and stationary mobile applications.
- Proportional DC actuators (combined with a control module) provide infinitely variable, step-less linear or rotary motion to control (fuel) levers or engine speed.
Next to standard design actuation devices, equipment is often fitted with custom-designed models. They are customized to directly fit and interact with OEM specific applications. Actuation linkage is required to connect the actuation device to the operated load and ensure optimal, accurate, and stable performance and compensate for misalignment. Commander modules are used in conjunction with DC solenoids to govern the solenoid's operation.
