The TRA series miniature motorized actuators are the latest addition to Newport's extensive range of precision positioning devices. They provide reliable motorized motion in a small diameter, lightweight package.
The TRA actuators incorporate an excellent space saving design that allows them to be used with a wide variety of linear stages, mirror mounts, and OEM applications. The TRA6 models provide 6 mm travel in a slim, 15 mm diameter housing and are the recommended choice for motorizing 561 series linear stages, 481 and RS65 rotation stages. The TRA12 models provide 12 mm travel and are compatible with Ultima and Suprema mirror mounts, ULTRAlign, 460A series linear stages, and other devices with up to 12 mm travel. The TRA6 and TRA12 are also mechanically compatible with other Newport mechanical products, but due to the limited travel range of the actuator, the total travel range of the mechanics may not be achieved. The TRA25 provides 25 mm travel in a slightly larger package and is the recommended choice for motorizing longer travel linear stages and other devices with longer travel range.
To provide the best fit for your application, TRA actuators are available in stepper, stepper vacuum and closed-loop DC servo motor versions.
All TRA actuators include integrated optical limit switches. These highly reliable switches not only protect your investment from over travel damage, they also provide a method for repeatable referencing/homing, for instance after shut-downs.
TRA actuators also feature a hard-coated steel ball tip that minimizes contact surface wear compared to other designs that use regular steel ball tips.
