5MM Precision Screw Slider Stepper (2Phase 4Wire) with Planetary Gearbox — Compact Moving Block for DIY Phone Camera and Precision Positioning Why you need this Precise linear motion in a compact package: the 5MM precision screw slider converts rotary motion from a 2phase 4wire stepper into reliable, repeatable linear travel, ideal when small, accurate movements matter. Higher torque and finer control: the integrated planetary gearbox increases output torque while reducing output speed, letting you make smaller incremental movements and hold position with less motor strain. Ready for DIY and prototyping: designed for hobbyists, camera builders and small automation projects that require a small moving block and easy integration with standard stepper motor systems. Key benefits at a glance Accurate linear positioning for focus, microadjustments, or guided motion. Compact footprint suited to phone camera rigs, tabletop devices, and compact assemblies. Uses a common 2phase 4wire stepper interface for straightforward driver compatibility. Planetary gearbox for improved torque and smoother, controlled movement. Main features and attributes Functionality: Rotarytolinear actuator using a precision 5MM screw and a moving block driven by a stepper motor with an attached planetary gearbox. Motor type: 2phase 4wire stepper configuration — compatible with standard bipolar stepper drivers and microstepping controllers. Drive reduction: Planetary gearbox provides gear reduction to increase torque and refine positional resolution (gear ratio dependent on specific unit). Moving block: Provides guided linear travel along the screw for mounting small loads or camera modules. Size reference: Designed around a 5MM precision screw for compact linear displacement and fine control. Performance: Suited to lowspeed, precision applications where small incremental movement and holding capability are required. Ease of integration: Can be incorporated into DIY phone camera rigs, minisliders, microassemblies, and robotic fixtures. Two to three practical use cases Phone camera focus and macro positioning: Add smooth, precise focus or framing adjustments to phone camera rigs. The small moving block and fine screw control make it easy to build compact slider or focusshift mechanisms for timelapse and macro photography. Miniature linear actuators in prototyping: Use as a compact actuator for hobby robotics, precision alignment of sensors, or small lab fixtures that need repeatable linear travel with controlled speed and torque. Automated microadjustments for optical modules: Ideal for adjusting small lenses, mirrors, or sensor positions in compact optical assemblies where space is limited but precise positioning is required. Compatibility and integration notes Designed for use with standard 2phase 4wire stepper driver setups (bipolar drivers). Check your driver/controller voltage and current ratings for compatibility with your specific motor/controller pair. Mechanical mounting and electrical connections will depend on your assembly and chosen controller; suitable for hobby and prototyping environments where small linear actuators are needed. What makes it unique Combination of a 5MM precision screw, moving block and a stepper with planetary gearbox in a single compact component tailored for smallscale DIY and camerarelated projects. Built to provide finer control and increased torque compared with directdrive small steppers alone, without significantly increasing footprint. Ordering guidance Ideal for hobbyists, camera builders, prototypers, and small automation projects seeking precise linear motion in a compact assembly. Verify controller compatibility (stepper driver voltage/current and wiring for 2phase 4wire motors) before installation. Includes Precision screw slider assembly with moving block, 2phase 4wire stepper drive interface and planetary gearbox as described in the product title. If you need compact, accurate linear motion for a phone camera rig or a precision DIY project, this 5MM precision screw slider with a 2phase 4wire stepper and planetary gearbox provides a practical, easytointegrate solution.
