External limit switch kit. To understand how limit switches work and how to wire them up we made a blog post with some instructions on how to do this. Click here to read our article on How to wire an Actuator with an External limit switch.
It is sometimes not possible to source a linear actuator which has the exact stroke length which you require, and sometimes the stroke length will vary with use. Firgelli Automations provides a solution for this, where you can purchase one actuator and shorten its stroke from factory by adding an external limit switch. These switches are very simple to hook up and will stop the actuator from moving past a set position. You will need a crimping tool or soldering iron, and heat shrink tube/electrical tape for insulation.
When procuring an actuator, this is typically a good investment in case the stroke needs to be adjusted once installed, and a replacement actuator is not feasible.
