Upgraded LAR31 Series of Linear and Rotary Actuators

The SMAC LAR31 series electric linear and rotary actuator is equipped with a standard encoder resolution of 5µm, with options of 1µm, 0.5µm and 0.1µm resolutions, and repeatable positioning to +/- 2 encoder counts. Further to this, highly accurate placement with shaft run-out ≤ 10um. The unit has no backlash, low repeatable friction and very low hysteresis. The LAR31 series actuator is compact measuring only 140mm x 77.25mm x 35mm with stroke length 30mm, and 180mm x 77.25mm x 35mm with stroke length 50mm. The actuator can easily be programmed to control force/torque, position and velocity in all axes at the same time. This enables the ability to press with specific force and measure displacement.

The unit offers multi-functionality with the ability to assemble and test components, with additional life test and measurement functions in one single unit. The system has the significant advantage of low repeatable friction.

The actuator also has SMAC's unique Soft-Land function which enables the unit to gently land on a surface and then apply the specific force required to set the part. This is ideal for handling fragile components without damage.

This SMAC solution is highly cost efficient has now been used in a number and variety of PCB assembly applications across the world.
