Compact, precise linear motion for small DIY projects and camera rigs. This 5MM Precision Screw Slider integrates a 2phase, 4wire stepper with a planetary gearbox and a moving block to deliver smooth, repeatable linear positioning for phone cameras, small robotics, and precision mechanisms. Why you need it Achieve accurate micropositioning: the 5mm precision screw converts rotary steps into fine linear movement for reliable, repeatable placement. More torque and finer control: the integrated planetary gearbox increases output torque and resolution so the stepper can move heavier loads or make smaller increments without losing steps. Ready for DIY use: a compact moving block and standard 2phase 4wire wiring make this module easy to integrate with common stepper drivers and microcontrollers. Key benefits Smooth linear travel for phone camera sliders, autofocus rigs, and compact actuation tasks. Higher holding torque and step resolution thanks to the planetary gearbox—reduces stalling and improves positional accuracy. Simple electrical interface: standard 2phase, 4wire stepper configuration for broad compatibility with hobby and prototyping electronics. Key attributes Lead/Size: 5MM precision screw for fine linear displacement and consistent pitch. Motor type: 2phase, 4wire stepper motor—bipolar configuration for precise closedloop or openloop control. Gearbox: Integrated planetary gearbox to boost torque and resolution while maintaining compact form. Moving block: Builtin carriage for mounting small loads such as phone mounts, camera adapters, or sensor assemblies. Functionality: Converts stepper rotary motion to accurate linear travel; suitable for continuous or intermittent motion in small systems. Compatibility: Works with standard bipolar stepper drivers and common microcontroller platforms used in DIY projects. Typical applications Phone or small camera slider: Create a compact, motorized slider for timelapse, smooth pans, or automated framing on smartphones and small cameras. DIY robotics and automation: Use as a precise linear actuator for grippers, sensor positioning, or small robot joints that require compact linear motion. Optical and focus adjustment: Integrate into focus stacks, lens adjustment rigs, or other precision positioning tasks where small, repeatable linear movement is required. What makes it practical Compact, integrated design reduces the need for external reduction stages. Standard stepper wiring and form factor simplify electronic control and mounting. The moving block provides an easy mounting point for payloads without extra machining. Integration notes Use with bipolar/2phase stepper drivers designed for 4wire motors. Mount the moving block to your payload using appropriate screws or clamps; ensure alignment with the screw axis to avoid binding. For performance, match driver current and stepping resolution to your application needs. This module is designed for hobbyists and makers who need a compact, reliable linear actuator with precision screw motion, planetary gear torque, and a readytouse moving block for phone camera and smallactuator projects.
