Cognex Cognex home page SMAC manufactures programmable electric actuators based on moving coil technology. These actuators are unique in that force, position and speed are totally programmable. They are designed to perform at exceptionally high speeds or very low speeds and with sub-micron accuracy and repeatability. This makes them ideal for a wide range of positioning, measuring, inspection and pick and place applications, particularly where 100% verification is required.

Programmable Electric Cylinders

SMAC Cylinder

SMAC Electric Cylinders have been designed with the most demanding of automation tasks in mind and are the first real linear motors to challenge pneumatic devices. They offer long life and much more precise and repeatable force control and positioning than conventional pneumatic devices. The conventional shape and multiple mounting points allow the electric cylinders to be directly retrofitted in most cases.

Linear Actuators

SMAC Linear ActuatorsSMAC provides a comprehensive selection of electric linear actuators, ranging from units with 5mm stroke in a compact unit only 10mm in height, to units with 150mm of stroke length or up to 500N peak force. As with all SMAC actuators, the LAL series linear actuator has the unique ability to enable free and independent control of velocity, position and force simultaneously. Further to this, the SMAC patented "Soft-Land" function is incorporated to allow delicate and controlled force when landing on fragile components.

Linear Rotary Actuator

Linear Rotary Actuators

SMAC provides a comprehensive selection of combined linear and rotary actuators with either direct drive or gearbox equipped rotary units. They can easily be programmed to control force/torque, position and velocity in all axes at the same time. The actuator has SMAC's unique "Soft-Land" function which enables the unit to gently land on a delicate component with a controlled force to avoid damage of both the component and the actuator. This makes them ideal for applications such as pick and place and assembly.

Linear Slide Actuators

SMAC Linear Slide Actuator

SMAC provides a comprehensive selection of electric linear slide actuators. The slide versions are based upon on the LAL and LAC series linear actuator and their performance characteristics are largely the same. They are compact in overall size and, and as with all SMAC actuators have a combination of force, position and velocity control with feedback. High or low speed and precise positioning with high repeatability make them ideal for applications such as parts feeding, scanning, testing, and measuring in wide range of industries.

SMAC Grippers

SMAC electric grippers incorporate programmable speeds, positions and forces with data feedback. The ability to independently control each jaw allows precise force control, measurement and positioning. This makes them ideal for a wide range of positioning, measuring, and inspection applications, particularly where 100% verification is required. Unit range is from with 5mm stroke in a compact overall size 55x70x17 with a 1 micron encoder as standard.

XY Stages

XY Stages

SMAC provides high-precision and high-speed XY stages. SMAC virtues of a direct drive zero backlash system, which can be controlled with great accuracy and repeatability. SMAC XY stages are equipped as standard with 5µm encoder with options down to 0.05µm encoder resolution for ultra precise positioning and scanning for industries such as bio-science, medical and photonics. The capability of controlling the velocity, acceleration, positioning and force of each axis independently, gives you a flexible and accurate tool.

Controllers & Amplifiers


SMAC supplies a range of single and multi-axis controllers together with stand alone amplifiers and stepper driven drivers. Controllers are programmed by mnemonic type command instructions via an RS-232 interface into NVRAM and allows code to be stored in non-volatile RAM, which is then used to enable movements to be made in three different modes. They require no supplementary software.
