ASI’s LS Series of Linear Stages provide sub-micron accuracy, deriving their precise control by using closed-loop DC servomotors and employing high-resolution rotary encoders for positioning feedback. An optional linear encoder can be added to the unit to provide even greater positioning accuracy. The stages utilize crossed-roller slides, precision lead screws and zero-backlash miniature geared DC servomotors for smooth and accurate motion. The units offer precise travel in a range of 50 mm to 200 mm. Longer models can be ordered as well. These stages can be used vertically and horizontally and can carry vertical loads up to 4.5 Kg (10 lbs) and horizontal loads over 45 Kg (100 lbs). Standard and OEM configurations are available.
