The Series 17000 open-frame XY stages are designed with a low height profile, for optical applications and to fit under most microscopes. The design allows access through the aperture from upper and lower positions. Cross-roller bearings and ground ballscrews give excellent straightness and flatness characteristics with high accuracy and repeatability. Stepping motor or servo motor control is available, with Limit and Datum switches fitted as standard. All motor, switch and encoder connections are made through D Type connectors on each axis.
