Does anyone make a "positioning cylinder" like the Festo DDPC but with a digital encoder feedback ?
I have an application where a 0.0005 mm pencil probe is overkill, but a 0.1 mm analog cylinder feedback is insufficient.
I'd like to be able to get 0.001 inch accuracy out of the cylinder, with an interface over SSI, IOLink, or EtherNet/IP.
The application will be an oppositional probe arrangement for measuring material thickness. I think I want a "servo pneumatic" system because I need to move relatively quickly through several inches (past a holding frame) and then slow down and reduce pressure right before I touch the part.
Festo is our usual brand for pneumatics, but we're open to SMC and anything that can be bought Stateside and connected to ControlLogix.
