LTA SeriesP R E C I S I O N M O T O R I Z E D A C T U A T O R S

LTA actuators are designed to fit into existing manual stages and other opto-mechanicalcomponents directly replacing manual micrometers. The LTA series features a space-savingdesign that reduces the actuator length by 50% and minimizes the unwanted effects ofcantilever loads on micro-positioning equipment. The non-rotating tip prevents wear andavoids periodic motion variations which can be caused by variable contact between a rotatingtip and its mating surface.

Precision motion is accomplished through a miniature DC servo motor with optimized outputtorque. This allows for faster motion and high load capacity. The LTA-HL is recommended forheavy load applications. It features a robust, 8 mm diameter rod and a M12-0.5 mountingbezel that is compatible with the UMR8 and MVN80 linear stages. The LTA-HS is optimizedfor high-speed applications and provides a longer travel range. The mounting interface of theLTA-HS is compatible with a large number of both Newport and non-Newport manualcomponents.

The LTAHSPPV6 and the LTAHLPPV6 were designed specifically for vacuum applications up to10-6hPa. These are comparable to the LTA-HS, and the LTA-HL respectively, but feature aminiature stepper motor with an encoder for reliable positioning.

Common to all models is a movable limit switch that prevents over-travel. The switchpositions can be changed in minutes to adjust the maximum travel position. A manualadjustment knob permits quick positioning of the actuator when the motor is off. A scaleindicates coarse actuator position in both millimeters and inches.

For compatibility with other Newport manual stages or opto-mech products, refer to themotorized actuator section of www.newport.com.

• Up to 50 mm travel in a space saving design

• Non-rotating tip improves motion smoothness and has nowear

• Exceptional Minimum Incremental Motion

• Adjustable limit switch prevents damage from over-travel

• Convenient manual positioning knob

• Vacuum versions with encoders

The LTA Series actuator is compatible with most standardNewport manual stages and opto-mechanical componentslike the 426 Series translation stage.
