Voice Coil Positioning Stage, VCS20-020-CR-01-SV
The VCS20-020-CR-01-SV voice coil positioning stage uses H2W voice coil motor NCC20-18-020-1A to generate a continuous/peak force of 2.0 lbs [8.9 N]/6.0 lbs [26.7 N] with a total stroke length of 2.0 in [50.8 mm]. The 1.0-micron resolution encoder allows for precise positioning. It comes supplied with a high accuracy crossed roller bearing. The magnet housing is the moving part of the assembly so that there are no moving (flexing) cables in the system. The voice coil motor has been mounted to the side of the bearing assembly in order to reduce the overall height and length of the system. This voice coil positioning stage has been manufactured using low-outgassing materials as selected by NASA in order to make it vacuum compatible.

For long stroke, compact size positioning stages please see our Single Rail Positioning Stages.
