TRA Series Compact Motorized Actuators

Product catalog summary

Overview: The document provides detailed information about Newport's TRA series of compact motorized actuators, which are designed for precision positioning in various applications. These actuators are a cost-effective alternative to the CMA series and are available in different models with varying travel ranges and motor types.

Specifications: The TRA series includes models with travel ranges of 6 mm, 12 mm, and 25 mm. They are available in stepper, stepper vacuum, and closed-loop DC servo motor versions. Key specifications include a drive screw pitch of 0.5 mm, a reduction gear ratio of 1:256, and integrated optical limit switches for protection and repeatability. The actuators are made from aluminum and feature a hard-coated steel ball tip to minimize wear.

Design and Compatibility: The TRA actuators are designed to be compact and lightweight, making them suitable for use with a variety of linear stages, mirror mounts, and OEM applications. They are compatible with Newport's mechanical products, although the total travel range may be limited by the actuator's range.

Performance: The actuators offer a resolution of 0.0305 μm for the TRA-CC model and 0.0977 μm for the TRA-PP model. They guarantee uni-directional and bi-directional repeatability of 2 μm and 3 μm, respectively, with a maximum speed of 0.4 mm/s, which may be reduced for higher axial loads.

Applications: The TRA series is recommended for motorizing various stages and mounts, including the 561 series linear stages and 481 and RS65 rotation stages. They are also suitable for vacuum applications with specific models designed for such environments.

Ordering Information: The document lists various models of the TRA series, each with specific features such as connector types and vacuum compatibility. It also provides recommended motion controllers and drivers for each model.

Contact Information: The document includes contact details for Newport Corporation's global offices, including phone numbers and email addresses for different regions.

They provide reliable motorized motion in a small diameter, lightweight package and are a lower cost alternative to the popular CMA series. 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 mechanical 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. • Up to 25 mm travel in a light, compact design • Replaces manual micrometer drives with similar form factor • Stepper, stepper vacuum, and closed-loop DC servo motor versions • Integrated limit switches prevent component and motor damage TRA Series Base Material Aluminum Drive Mechanism Rolled lead screw Drive Screw Pitch (mm) 0.5 Reduction Gear 1:256 Feedback CC: Motor mounted rotary encoder, 64 cts/rev.
