Especially the first one is really nice since it has a built in encoder and a controller with RS232 interface. However, the downside is that these have a starting price around $1,700.
The specs should be something like:
- 100 mm travel
- 1 mm precision
- RS232 / USB interface
- Speed is not critical
- The load will not be large (<5N)
Does anyone have any suggestion how you could do this on a budget of say $500? Or does anyone have a suggestion for something completely different with the same function?
