Compact 5MM precision screw slider with integrated 2phase 4wire stepper and planetary gearbox — designed for accurate, repeatable linear motion in DIY phone and camera projects. Key benefits Precise linear positioning: the 5MM precision screw slider and moving block deliver fine, repeatable motion for small adjustments and smooth travel. Higher torque, smoother motion: the builtin planetary gearbox increases output torque and reduces vibration, making the assembly better suited to loadbearing micro applications. Easy integration with stepper control electronics: the 2phase 4wire stepper configuration works with standard bipolar stepper drivers and common controller boards, enabling straightforward electronic control. Compact and DIYready: small form factor and moving block design let you fit this unit into phone camera rigs, compact sliders, and other tightspace projects. Key attributes Functionality: Linear screwdriven slider with moving block for controlled linear displacement; motorized by a 2phase 4wire stepper for precise, incremental motion. Drive type: 2phase 4wire stepper motor — compatible with standard bipolar stepper drivers and control systems. Gearbox: Integrated planetary gearbox to boost torque and smooth motion under load. Size: 5MM precision screw slider (as specified in the product title) — designed for compact applications. Use: Intended for DIY projects where small, accurate linear movement and reliable motorized control are required, such as phone and camera accessories. Integration and compatibility notes Requires a stepper motor driver and controller that support 2phase 4wire (bipolar) stepper motors. Wiring follows a 4wire stepper configuration; confirm driver wiring sequence during installation. Designed for compact assemblies; plan mounting and clearance around the moving block and gearbox. Typical applications Smartphone camera slider: Add motorized, precise linear motion to phone camera rigs for smooth timelapse and tracking shots. Micro focusing mechanism: Use as a repeatable focusing or microadjustment stage in compact camera modules or DIY optics setups. Small automation and prototyping: Ideal for hobby robotics, modelmaking, and other projects that need compact, controllable linear actuation. What this product solves Eliminates manual adjustment limitations by converting rotational stepper motion into precise linear displacement with the screw slider and moving block. Improves loadhandling and motion quality through the planetary gearbox, reducing missed steps and vibration in smallscale applications. Provides a compact, motorized solution suitable for integration into mobile camera rigs and other spaceconstrained designs. Package and installation tips Verify driver compatibility and current settings for the motor to prevent overheating or missed steps. Secure the moving block and gearbox mountings to minimize mechanical play and ensure accurate travel. Test motion range and end limits before full operation to avoid overtravel. This 5MM precision screw slider with 2phase 4wire stepper and planetary gearbox is a compact, motorized linear solution for DIY phone camera projects and smallscale precision applications that need dependable, smooth motion and straightforward electronic control.
