H2W Introduces Miniature Voice Coil Positioning Stage
The engineers at H2W have developed their most compact voice coil positioning stage to date. The customer for this stage requested that it fit within a volume of 1.6 cubic inches (40 cubic mm) cube volume. The application required an ultra-compact stage due to space restrictions in their auto-focus mechanism.
The voice coil positioning stage (VCS02-001-CR-01-MC) is a closed loop system that can be used for high speed positioning and auto-focusing applications. The stage is driven by a NCC type actuator (NCC02-07-001-1R) and is guided by a precision linear crossed roller bearing. The voice coil has a 0.20" [5.1 mm] stroke; generates 0.26 lbs [1.16 N] of continuous force and 0.78 lbs [3.50 N] of peak force. It includes a 1 micron resolution magnetic linear encoder. Voice coil positioning stages are ideal for applications that require quick, short moves with fast settling times.
