Moticont (Van Nuys, CA) has introduced the HCDS-051-051 Series of eight Linear Open Aperture Voice Coil Stages. These compact open aperture stages have a small footprint of just 10.500 in. (266.7 mm) long x 4.000 (101.6 mm) wide x 3.755 in. (95.4 mm) high. Linear DC motor driven stages (also known as moving coil) are clean, quiet and efficient, with low inertia, high acceleration and high speed. Designed for closed loop servo operation, an integral quadrature optical encoder with differential outputs is included. Each stage has a built-in home switch for accurate initialization upon power up. Open aperture stages are ideal for laser drilling and milling, optical focusing, testing, laser steering, mirror positioning, scanning, oscillation, switching, sorting, pick-and-place, and the pass through of fiber optics, electrical, and air lines.
