High load LTA Series actuator with 25 mm travel. Recommended for heavy load applications, the LTA-HL features a robust, 8 mm diameter rod and a M12-0.5 mounting bezel that is compatible with the UMR8 and MVN80 linear stages. LTA actuators are designed to fit into selected manual stages and other opto-mechanical components as direct replacement for manual micrometers.[Refer to the actuator compatibility table.] Features a space-saving design with the motor and lead screw mounted side-by-side. This reduces the actuator length by 50% and minimizes the unwanted effects of long 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. A movable limit switch 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.
