Overview

1.1. Environmental Specifications

W A R N I N G : Do not expose this product to environments or conditions outside of the listed
specifications. Exceeding environmental or operating specifications can cause damage to the
equipment.
Table 1-2: Environmental Specifications
Ambient Operating: 10° to 35° C (50° to 95° F)
Temperature The optimal operating temperature is 20° C ±2° C (68° F ±4° F). If at any time the
operating temperature deviates from 20° C degradation in performance could occur.
Storage: 0° to 40° C (32° to 104° F) in original shipping packaging
Humidity Operating: 20% to 60% RH
Storage: 10% to 70% RH, non-condensing in original packaging. The stage should be
packaged with desiccant if it is to be stored for an extended time.
Altitude Operating: 0 m to 2,000 m (0 ft to 6,562 ft) above sea level
Contact Aerotech if your specific application involves use above 2,000 m or below sea
level.
Vibration Use the system in a low vibration environment. Excessive floor or acoustical vibration
can affect system performance. Contact Aerotech for information regarding your
specific application.
Protection The ANT95L stages are not suited for dusty or wet environments. This equates to an
Rating ingress protection rating of IP00.
Use Indoor use only

1.2. Accuracy and Temperature Effects

Aerotech products are designed for and built in a 20°C (68°F) environment. Extreme temperature changes
could cause a decrease in performance or permanent damage to the ANT95L. At a minimum, the
environmental temperature must be controlled to within 0.25ºC per 24 hours to ensure the ANT95L
specifications are repeatable over an extended period of time. The severity of temperature effects on all
specifications depends on many different environmental conditions, including how the ANT95L is mounted.
Contact the factory for more details.
The thermal expansion coefficient of the encoder scale is 3.25 ppm/°C. Travel will increase or decrease at
this rate as the temperature of the encoder scale temperature deviates from 20°C (68°F).
The accuracy specification of ANT95L series stages is measured 25 mm above the table with the stage in
an unloaded condition. The stage is assumed to be fully supported by a mounting surface meeting or
exceeding the specification in
