HAYDON dual motion actuators are based on unique, patented designs and incorporate Haydon’s proven motor technology.
Three sizes are offered from 35 mm to 57 mm, providing independent linear and rotary motion from a compact package.
In certain applications, it is required to have both rotary and linear motion. Such an application, for example, is in the robotic picking and placing of components where it may be required to axially move a component to an insertion position and then rotate the component to screw it in place.
The linear/ rotary unit allows for simplified system design and a reduction in the number of components. It is ideal for use in tight fitting applications requiring precise two degrees of freedom, controllable motion, pick and place equipment, robotics, and a wide array of instrumentation.

Programmable electric linear rotary actuators with either direct drive or gearbox equipped rotary units. Fully programmable in force/torque, velocity and position with 100% data capture and feed back facility. Standard linear resolution is 5micron with 1micron and 0.5micron options available.
The SMAC unique “Softland” routine within the actuator allows the rod to approach at high speed then land on the surface of a component with a low programmable force. This unique feature is extremely useful whenever delicate or high value components are being handled.
SMAC electric actuators are used widely in packaging, labelling, automotive, SMT, robotics, pharmaceutical, medical assembly, laser cutting, high speed scanning, glass cutting, dispensing, switch testing, spot welding, soldering & measuring applications to name but a few.
