HCDS-051-051-01 Hollow Core Linear Voice Coil Stage Series

Series Overview

The HCDS-051-051-01 series consists of direct-drive hollow core linear voice coil stages engineered for rapid, precise, and repeatable positioning. The guided moving table surrounds a central aperture, allowing optical beams, illumination, wiring, tubing, or other components to pass through the stage.

Key Benefits

• Direct-drive motion with zero mechanical backlash and no cogging
• Integrated linear guidance for a ready-to-use positioning stage
• Quadrature optical encoder feedback and built-in home switch
• Multiple aperture, force, travel, bearing, and encoder-resolution configurations
• High acceleration, rapid settling, quiet operation, and long service life
• Pre-drilled mounting features for straightforward installation

Applications

Typical uses include optical focusing, laser beam steering, mirror positioning, scanning, switching, inspection, alignment, metrology, medical instrumentation, laboratory automation, vibration control, precision assembly, and research systems.

Selecting a Model

Use the model listings below to compare range of motion, continuous and intermittent force, aperture diameter, bearing configuration, encoder resolution, and connection options. Review the individual product page and datasheet before selecting a controller, amplifier, cable, or return-spring option.

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.

Each HCDS-051-051 Series stage has precision threaded mounting holes for tooling or fixtures, and has a linear travel of 0.70 in (17.8 mm), a plug-and-play wired connector, and convenient mounting holes for easy integration into new or existing applications.

The stages are available with a resolution of 29.5 microns, 25.4 microns, 12.7 microns, and 1 micron. Additionally, each stage is available with a continuous force of 5.2 lbs (23.1 N) and a peak force of 16.4 lbs (72.9 N), or a continuous force of 6.3 lbs (28.0 N) and a peak force of 19.9 lbs (88.6 N), and an optional return spring. There two sizes are available for the diameter of the aperture, 0.5 inch (12.7 mm) and 0.75 inch (19 mm).
