Linear and Rotary Actuators with Optional Position Feedback

Linear Actuators
The  Linear Actuator family consists of modular components made up of end plates, carriage plates,  carriage top plates, motor mounts, flexible couplers, steel shafts, lead screws and thrust nuts.  All the mounting and end plates are made from T6061 Aluminum.  Shafts are steel and available in various lengths.  These components can be mixed to create linear actuators of different lengths and load capacities.  Linear actuators are available assembled or as individual components.

Rotary Actuators
The Rotary Actuator family consists of stepper motor driven rotary plates with different radius.  The coupling between motor and disk is belt driven resulting in zero backlash operation.  Dual belt drives are available for higher torque applications.  The Rotary Actuator product family is under development.

Magnetic Linear Position Feedback
Low cost magnetic linear position sensors (AS5311 with quadrature output) were recently introduced that measure the position on a specially magnetized 2mm dipole magnetic strip with a resolution of 2 micron(0.000078740in).  An Imperial 1/4-20 thread moves 0.00025 inch per full step or 0.00003125 inch per 1/8 microstep so the position sensor will be able to detect a 2 microstep error.  Many of the Smart Controllers support quadrature inputs.  The MS25U, Quad3X and Quad6X bring quadrature decoding capability to the desktop as single, three and six axis options.
