Yeah, I’ve worked with micro linear actuators in a few production-line upgrades over the past couple of years. One specific use case that comes to mind was in a quality control unit at a pharma plant. We had to automate a tiny flap that would open and close based on whether a vial passed visual inspection — space was super limited and the PA-07 micro actuator was just small and reliable enough to fit the job. It handled repetitive cycles like a champ. Another place we’ve used them is inside small sensor housings where regular actuators simply don’t fit. These things are great where you need controlled, quiet motion and don’t have room to spare. If you're thinking about this route, I’d recommend starting here micro linear actuators:
