Linear Actuator with Flexible Stroke & PCB Endstop — 3D CAD Download
Discover a practical linear actuator CAD model that features a flexible stroke and a mechanical limit switch mounted on a PCB. This assembly was created for easy integration with common motion hardware such as V-slot profiles, MG12H linear guides, and T8 lead screws. The downloadable package typically includes STEP/STEP AP203 files, assembly parts, and measurements useful for CNC or 3D-printed fixtures.
Overview
This linear actuator design is ideal for mechatronics projects, small automation tasks, and classroom demonstrations where a compact endstop and adjustable travel are required. The model demonstrates how to mount a mechanical endstop (limit switch) directly on a PCB and how to couple the mechanism to standard profiles (V-slot) and MG12H rails.
What’s included
- Full assembly with parts (STEP / STL where available)
- Mounting details for V-slot and MG12H guides
- Endstop (mechanical limit switch) mounting on PCB
- Dimensions and recommended hardware (T8 lead screw, stepper coupling)
How to use
Download the files, open the assembly in your CAD software, and verify dimensions against your selected linear guide and lead screw. Use the included PCB mounting holes to fit a small switch for endstop detection — perfect for low-cost motion control and prototyping.
