LEFS Ball Screw Slider, High Performance with Battery-less Absolute Encoder

LEFS*G is a high performance version of the standard slider, also equipped with the battery-less encoder onboard the motor.  This encoder allows the actuator to be powered down without losing its positional awareness.  Further, battery replacement and recycling are eliminated.  Load capacities have increased 9-50%.  Cycle time is dramatically reduced by a combination of higher maximum speed and acceleration/deceleration.  Note that maximum speed gains are primarily in the 50-400mm stroke range, ranging from 5-36% faster depending on motor size and ballscrew pitch.  The LEFS*G actuator pairs with a high performance step motor controller, the JXC*H.  Actuator dimensions and mounting are identical to the standard LEFS, allowing an updgrade for exisiting equipment
