Newport releases its NSA12 actuator with a new controller, the CONEX-PP. The CONEX-NSA12 is a miniature motorized linear actuator with an iPP stepper motor controller. The actuator features an open loop stepper motor that provides 11 mm travel and can be used for loads up to 28 N. It offers an economical solution for motorizing mirror mounts, rotation stages, linear stages and other manual motion devices. Due to its compact size, the actuator can be used for space limited locations. A vacuum compatible version, the Conex-NSA12V6, is also available.
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.
