CONEX-NSA12 Motorized Actuator
Designed as micrometer replacement, the CONEX-NSA12 linear actuator is ideal for remote adjustment of sensitive, hard-to-reach optical mounts. Typical applications include optimizing the alignment of a laser cavity, zeroing in on coherence lengths, or just adjusting the pointing of a beam over a long distance.
The CONEX-NSA12 provides 11 mm motorized travel with sub-micron resolution. It can drive up to 28 N load. With its backlash eliminating spring mechanism and 5/32” non-rotating chromevanadium steel ball bearing this actuator is ideal for applications that require repeatability.
The CONEX-NSA12 is easily mounted via its 0.375” x 40 pitch threaded shaft. This mechanical interface is compatible with many Newport mounts and manual stages. A mounting nut and wrench are included.
