Motorized Actuator, High Load, 25 mm Travel, Vacuum Compatible

The Vacuum compatible High load LTAHLPPV6 actuator with 25 mm travel. Recommended for heavy load applications, the LTAHLPPV6 features a robust, 8 mm diameter rod and a M12-0.5 mounting bezel that is compatible with vacuum versions of the UMR8 and MVN80 linear stages. LTA actuators are designed to fit into existing manual stages and other opto-mechanical components as direct replacement for manual micrometers. Featuring a space-saving design ideal for limited space in vacuum chambers, the LTA motor and lead screw are mounted side-by-side. This not only reduces the actuator length by 50%, but also minimizes the unwanted effects of long cantilever loads on micro-positioning equipment.  Precision motion is accomplished through a miniature stepper motor with optimized output torque. This allows for faster motion and high load capacity. A movable limit switch prevents over-travel. The switch positions can be changed in minutes to adjust the maximum travel position.
Note: The connector supplied with the actuator is not vacuum compatible due to various feed-through configurations and customer preferences. Please contact Newport for vacuum compatible connector options

Manual Adjustment Knob

LTA Series motorized actuators provide a manual adjustment knob which permits quick positioning of the actuator when the motor is off.

Scale Position Indication and Limit Switch

LTA Actuators include a visible scale that indicates coarse actuator position in both millimeters and inches. Beneath the scale's window is an accessible trigger which, along with the Manual Adjustment Knob, can be manually set to limit the actuator's travel range.

Non-rotating Actuator Tip

LTA actuators feature a non-rotating tip that prevents wear and eliminates periodic motion variations when the actuator is moving.
