Linear voice coil actuator A-142

Ultra-Compact Motorized Air Bearing Linear Stage The A-142 miniature linear translation stage is a unique, high performance precision nanopositioning system, featuring a direct-drive voice coil linear motor, a high-resolution linear encoder and frictionless and stiff air bearing guides. It is ideally suited for maintenance-free, high duty cycle industrial scanning and positioning applications. The special design of this voice coil-driven stage does not use any internal moving cables. Miniaturized Stage Design for High Performance Linear Motion Despite its small size, this miniature linear translation stage provides high performance linear motion that cannot be met by conventional stages with mechanical bearings. Air bearing slides do not require lubricants and do not generate particles which makes them cleanroom compatible, another advantage in photonics, optics and semiconductor related test, metrology and alignment applications. Since the direct-drive, voice coil linear motor and the air bearings are completely maintenance-free and wear-free, this compact translation stage can be used in industrial, high throughput, 24/7 precision motion applications.
