Hello everyone,

I need to assemble a small motorized Z-axis stage to hold a load that is roughly 1 lb and needs a travel distance of at least 5-6cm and take up an area of preferably 4" x 4" or less, but some overlap is ok. So far all I have been able to find are very high-end, high-resolution motorized lab jacks from Thorlabs that are outside of my budget range (once you include the controller and everything). The budget for this is roughly $1000 or less. It only needs a resolution of ~0.1mm or so. I also want to control the motor controller using a LabVIEW program eventually so perhaps the controller can be a Phidgets since I know they have a LabVIEW library already.

I'm wondering if anyone can suggest an alternative solution perhaps using products available on Robotshop. It seems like a simple problem, I just need to be able to move an object (a small camera) up and down remotely using a small motorized system.

Thank you for your input, and let me know if you require any additional info.

Best regards,
Johnny5

You might consider an L12 linear actuator w/ 50mm stroke and an accuracy of 0.2mm. This can be controlled with something like the Phidgets servo controller. We don't carry any track-based actuators at this time.

Thank you, however I am having trouble finding the proper bracket for this particular model. Is it available on RobotShop?

There are some small metal mounting brackets included with each actuator.

Thank you for the assistance. I noticed that Firgelli also offers controllers that can be used with LabVIEW so that's great. Are the included brackets used to attach to the hole at the base of the actuator (in the blue area), or elsewhere? Because I noticed in the 3-D CAD of the actuator on the Firgelli website (http://www.firgelli.com/Uploads/PQ-12_IGES.zip) there is a small bracket already attached about mid-way up the actuator. Regarding attaching the end of the actuator to the object that needs to be moved, is there a standard pin to be used in the actuator hole or would I need to get that custom?

Last we checked, there are three brackets:
2x 90 degree brackets (for the ends)
1x rectangular tube clamp bracket (for holding the actuator in place)
