LTA actuators are designed to fit into existing manual stages and other opto-mechanical components directly replacing manual micrometers. The LTA series features a space-saving design that reduces the actuator length by 50% and minimizes the unwanted effects of cantilever loads on micro-positioning equipment. The non-rotating tip prevents wear and avoids periodic motion variations which can be caused by variable contact between a rotating tip and its mating surface.Precision motion is accomplished through a miniature DC servo motor with optimized output torque. This allows for faster motion and high load capacity. The LTA-HL is recommended for heavy load applications. It features a robust, 8 mm diameter rod and a M12-0.5 mounting bezel that is compatible with the UMR8 Double-Row Steel Linear Ball Bearing Stages and MVN80 Precision Vertical Travel Stages. The LTA-HS is optimized for high-speed applications and provides a longer travel range. The mounting interface of the LTA-HS is compatible with a large number of both Newport and non-Newport manual components.The LTAHLPPV6 and LTAHSPPV6 were designed specifically for vacuum applications up to 10-6hPa. These are comparable to the LTA-HS , but feature a miniature stepper motor with an encoder for reliable positioning. Common to all models is a movable limit switch that prevents over-travel. The switch positions can be changed in minutes to adjust the maximum travel position. A manual adjustment knob permits quick positioning of the actuator when the motor is off. A scale indicates coarse actuator position in both millimeters and inches.For other actuators, view our Motorized Linear Actuator Selection Guide.
