SMAC introduces the upgraded LAR31 series of linear and rotary electric actuators.
The LAR31 actuators have a vacuum built in the shaft through the rotary motor. The vacuum assures that any external particles such as dust are ejected through the other end, which prevents dust build-up in the unit.
The SMAC LAR31 series electric linear and rotary actuators are equipped with a standard encoder resolution of 5µm, with options of 1µm, 0.5µm and 0.1µm resolutions.
The unit has no backlash, low repeatable friction and very low hysteresis. The LAR31 series actuator measure either 140mm x 77.25mm x 35mm with a stroke length of 30mm, or 180mm x 77.25mm x 35mm with stroke length 50mm. The actuator can 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 low repeatable friction.
The actuator features SMAC's ‘Softland' 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 damages.
