Linear Motor Stages

The ANT95-XY and ANT95-XY-H dual-axis linear motor stages from Aerotech, Pittsburgh, PA, allow travel in X and Y dimensions. They allow critical elements such as orthogonality, straightness, and flatness to be optimized. The technology has no hysteresis or backlash, enabling 5nm resolution, 50nm repeatability, and 250m accuracy in both X and Y dimensions. Both the 25 × 25mm or 50 × 50mm travel options come with a 60mm profile height.

Cylinder Position Sensor

A magnetically actuated linear displacement sensor from Turck, Minneapolis, MN, the Q25L, detects piston position on pneumatic cylinders. Suited for applications requiring precise signal transmission over long measuring distances, it is available with measuring ranges of 100, 125, 160, and 200mm. By utilizing an external magnet as a position indicator, the sensor can be used in additional applications such as moving platforms, point line measurement, or other specially designed equipment where a cylinder is not present.
