The part of a hard disk to which the read/write arms attaches. All the heads are attached to a single head actuator, also called an actuator arm, that moves the heads around the platters.  Older hard [..]

Part of the firing mechanism in certain automatic firearms, such as trigger actuator, which slides forward and back in preparing each round to be fired.

A device that converts an electronic signal into a mechanical motion.

A device that introduces motion by converting electrical energy into mechanical energy in an electromechanical system. (An actuator may also stop motion by clamping or locking.) A dynamo is an example of an actuator.

A motorised device that drives a multi-satellite dish to allow it to point at different satellites.

A machine that is used to create an automatic and regular action in something.

A device that converts various forms of energy, when given an input, to rotating or linear mechanical motion such as a motor.

A device that creates mechanical motion by converting various forms of energy to rotating or linear mechanical energy.

A pneumatic device that converts air pressure into motion.

(n) a mechanism that puts something into automatic action

An actuator is the mechanical component used to manually turn a switch or circuit breaker on and off.

A device that creates mechanical motion by converting various forms of energy to rotating or linear mechanical energy.

A piece of equipment that allows a robot to move by conversion of different energy types such as electrical or mechanical processes using liquid or air. (Common Misspellings: actuater, actuattor)

That portion of a regulating valve, which converts mechanical fluid, thermal energy or electrical energy into mechanical motion to open or close the valve seats.

The mechanical interface between the basic switch contacts and the means of operation, such as the operator’s finger.

A device for converting hydraulic energy into mechanical energy, i.e., a motor or cylinder.

For servo systems, any device (such as a motor) that outputs mechanical motion using electricity as the power source.

a servomechanism that supplies and transmits a measured amount of energy for the operation of another mechanism or system.

A device that performs a mechanical action in response to an input signal, which may be electrical or fluidic.

A device that creates mechanical motion by converting various forms of energy to rotating or linear mechanical energy.

A device which performs a mechanical action in response to an input signal, which may be either electric or fluidic.

An actuator is used to convert an electrical signal into mechanical energy or other physical quantities. This makes it the opposite of a Sensor, which converts energy into electrical signals. Actuatio [..]

Part of an ultrasonic press performing a mechanical work, exploiting the compressed air energy.

The part of a switch that causes change of the contact connections (e.g., toggle, pushbutton, or rocker).

That portion of a regulating valve that converts mechanical fluid, thermal energy, or electrical energy into mechanical motion to open or close valve seats.

Mechanical device for moving or controlling a mechanism or system.

A device connected to the valve that allows remote movement of the valve. It can be an air, fluid or electrically powered device. Actuators may be used when valves are remotely located (e.g., on pipel [..]

A (hydraulic or electrical) device for the remote and/or automatic operation of a valve or choke.

A rod, mounted on the load frame that is driven up or down using servohydraulic force. The force required to drive the actuator is transferred to the specimen through the grips. Actuator applies to servohydraulic systems only. Note that the crosshead is fixed during a test on a servohydraulic system.

The part of a switch that is acted upon to cause the switch to change contact connections; for example, toggle, pushbutton, and rocker. The mechanism of the switch or housing which, when moved as inte [..]

The portion of a regulating valve, which converts mechanical, fluid, thermal, or electrical energy; into mechanical motion to open or close the valve seats or other such devices.

Mechanical part of a limit switch that uses mechanical force to actuate the switch contacts.

A power mechanism used to effect motion, or maintain position of the robot (for example, a motor which converts electrical energy to effect motion of the robot) (R15.07). The actuator responds to a si [..]

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system, for example by opening a valve. In simple terms, it is a "mover". An actuator requires a c [..]

The cam, arm or similar mechanical piece used to operate the contacts in a device

An actuator is a device that causes a valve to move from the open to the closed position or vice versa. Technically speaking: A component designed to provide the mechanical energy to physically move a connected device. Actuators are used extensively to move valves to their open and closed positions. Valve actuators can be pneumatic, hydraulic, or e [..]
