To prevent equipment damage from over-travel, the actuator includes a fixed, integrated minimum travel limit switch and a controller programmable soft limit for maximum travel. The NSA12 also features a non-rotating tip that prevents wear and avoids the periodic motion variations which can occur in other actuators with rotating tips. Furthermore, the actuator incorporates a mechanism that virtually eliminates backlash, which is crucial in applications like active beam alignment or optical tracking.
“Being Newport’s smallest and most economic actuator, the NSA12 is a flexible and easy solution to motorize high precision components”, says Beda Espinoza, Sr. Product Marketing Manager Motion at Newport. “In combination with the CONEX-PP integrated controller it does not require any setup and provides perfect control right out of the box. The supplied GUI can manage up to 4 daisy-chained CONEX-PP controllers or be launched several times for multi stage configurations with a USB hub.”
