Electric actuators are motor-driven components that drive or trigger other functions in a circuit. They use electrical input current - unlike hydraulic, pneumatic, thermal or magnetic actuators - and convert it to mechanical (linear or rotary/torque) energy for powering various sorts of control systems.
We stock a comprehensive range of electric actuators, controllers, switches and mounting accessories from trusted brands like Siemens, SMC, RS PRO and Actuonix.
Rod style electric actuators provide linear output forces (pushing, pulling or pressing a load). The rod extends/retracts in response to input current, acting on an attached load or one positioned such that it will be moved. They’re a popular alternative to pneumatic slide unit actuators, because the extent of motion for a rod-style actuator isn’t strictly limited by the length of its housing.
Electric rod actuators are simpler to install and maintain than equivalent hydraulic components, and often chosen where accurate end-to-end positioning, fast speeds or high forces are required. Miniature electric actuators are also available in rod-style configurations, reducing the need for awkward or bulky gears, motors, servos and linkages in smaller circuits such as robotics.
Rodless electric actuators can be belt-driven or screw-driven, and are often preferred in pick-and-place or sensor adjustment roles.They commonly use self-lubricating toothed belts or lead screw axes for smooth linear operation and quick installation, without the need for external lubrication. Defined stroke length makes them ideal in systems or machinery designed for lifting, stacking and testing.
Linear actuator switches can use latching, momentary, reed, or solid state mechanisms to trigger an actuator, with the best choice often depending on install location and environmental conditions.
Controllers and mounting equipment for electric actuators give precise control over the exact function and positioning of your actuator devices across a wide range of industrial and domestic systems.
