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. The non-rotating tip prevents wear and avoids periodic motion variations which can be caused by variable contact between a rotating tip and external contact surface. 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. A manual adjustment knob permits quick positioning of the actuator when the motor is off, with a visible scale that indicates coarse actuator position in both millimeters and inches. 


Can be ordered with a vacuum compatible 25pin SubD connector.


Note that the connector at the end of the cable is not vacuum compatible.

真空兼容高负载LTAHLPPV6执行机构，行程25毫米。推荐用于重载应用，LTAHLPPV6具有一个健壮的，直径8毫米的棒和M12-0.5安装边框，兼容UMR8和MVN80线性阶段的真空版本。LTA执行机构被设计成适合于现有的手动级和其他光学机械部件，作为手动测微仪的直接替代。具有节省空间的设计理想，在有限的空间在真空室，LTA电机和丝杆安装并排。这不仅使执行机构的长度减少了50%，而且最大限度地减少了长悬臂载荷对微定位设备的不良影响。非旋转刀尖防止磨损，避免了由于旋转刀尖与外部接触面接触变化而引起的周期性运动变化。精密运动是通过一个微型步进电机与优化输出扭矩完成的。这允许更快的运动和高负载能力。可移动的限位开关可防止行程过长。开关位置可在几分钟内改变，以调整最大行程位置。手动调节旋钮允许执行机构在电机关闭时快速定位，带有一个可见的刻度，指示在毫米和英寸的粗执行机构位置。

可以订购与真空兼容的25pin SubD连接器。

注意，电缆末端的连接器不是真空兼容的。
