TRB Compact Motorized Actuators
TRB linear actuators offer mid-range load capacity with a wide range of travel and motor choices, and can easily motorize manual positioners and mirror mounts with flexible cable routing and a non-reflective surface coating.

Manufacturer: Newport — USA
Overview
TRB linear actuators offer mid-range load capacity with a wide range of travel and motor choices, and can easily motorize manual positioners and mirror mounts with flexible cable routing and a non-reflective surface coating. They are available in both DC servo motor and stepper motor versions across three travel ranges. CONEX controller versions with integrated motion control electronics are also available.
Slim, Lightweight Design
The TRB series actuators feature a slim, lightweight design that allows them to be used in compact spaces with a variety of manual stages, mirror mounts, and OEM applications.
Hard-Coated Steel Ball Tip
TRB actuators feature a hard-coated steel ball tip that minimizes wear on the contact surface compared to designs using regular steel ball tips.
Optical Limit Switches
All TRB actuators include integrated optical limit switches to protect against over travel damage, and provide a method for repeatable referencing and homing after power up.
Flexible Cable Routing
The cable outlet of TRB actuators is located on the side, providing more flexibility for cable routing and management while reducing the overall length of the actuator compared to designs with a rear cable outlet.
