Picomotor Actuator, Ultra-High Vacuum, 0.5 in., 12x.5 mm Thread, Kapton

The 8321-UHV-KAP Ultra-High Vacuum Picomotor™ Actuator with Kapton Wires offers 0.5 inch (12.7 mm) travel and can be used in UHV environments (10-9 Torr) as well as for VUV/EUV applications. Similar to our 8301-UHV, it is now offered with Kapton wires while utilizing our patent pending strain relief mechanism. It is ideal for beam-steering and scientific vacuum motion-control applications. This actuator offers the same better than 30-nm resolution with minimal backlash along with excellent long-term stability and high stiffness, including the ability to maintain their set positions even in the power-off state.
<30 nm Positioning Resolution
Our Picomotor actuators have a step size of less than 30 nm per step, allowing for very small, controlled movements. Note that the step size for open-loop picomotors varies from step to step and between forward and backward directions, and is directly related to payload – hence, position feedback should be provided by an external signal when operating an open-loop picomotor. For vacuum applications requiring absolute position calibration and high repeatability, consider a Vacuum Compatible Closed-Loop Picomotor actuator.

Easy-to-Use, Flexible Controllers and Drivers
We offer both Open-Loop Picomotor controllers and drivers as well as Closed-Loop Picomotor controllers and drivers. You have two interface options with the controller system: hand pad or computer, both providing plug-and-play use. Alternatively for open-loop actuators, you may choose to use our TTL/Analog Picomotor driver.
