● Optional high-accuracy linear encoder

Construction Features
ATS150 series stages are machined from a special cast aluminum alloy to provide a high strength-to-weight ratio and long-term stability. The base is a box design that provides exceptional stiffness and stability.

ATS150 series stages employ a precision-ground ball screw that is pre-loaded to eliminate backlash, and its nut has wipers to prevent contamination and maintain high accuracy throughout the life of the stage. High quality, pre-loaded duplex bearings are used to eliminate axial play.

All ATS150 series stages incorporate Linear Motion Guide (LMG) bearings to provide high load capability and high stiffness. The LMG design provides a compact stage with continuous carriage support over the entire travel and good cantilevered load capability. Integral wipers on the bearing trucks help ensure stage travel life. Highly accurate optical limit switches and end stops are also standard.

Integral bellows-type waycovers protect the drive and bearing system from contamination. Metal surfaces are protected with an attractive clear anodized finish. Both metric (standard) and English mounting and bolt-hole patterns are available.

Linear Encoder
A precision noncontact linear encoder is an option. The encoder is mounted internal to the stage, protecting it from external contaminants and debris.

Motors and Drives
Included with all ATS150 series stages are Aerotech BMS series brushless rotary motors. This motor has all of the advantages of a brushless motor – high acceleration, no brushes to wear and lower heating – yet has zero cogging for extremely smooth motion and accuracy. Aerotech manufactures a wide range of matching drives and controls to provide a fully integrated and optimized motion solution.
