Product Description Specifications Downloads Quote / Order

Product overview

Thanks to a compact high-performance linear motor with voice coil drive and air-bearing guides, the A-142 offers maximum precision for high dynamic applications. The combination of the noncontact components results in a frictionless motion platform that offers top performance, quality, and lifetime.

Accessories and options

PIglide filter and air preparation kits
Pneumatic counterbalance for vertical mounting

Application fields

The linear stage is ideally suited for high-precision applications, such as metrology, photonics alignment systems, optics positioning, and scanning. The noncontact design is ideal for cleanroom applications. Electrical cables are not moved.
