Compact 5mm precision planetary gearbox with 2phase, 4wire stepping electronic starter and integrated linear screw metal slider — engineered for precise, repeatable motion in DIY camera and small automation projects. Key benefits Precise, repeatable positioning: The 5mm precision planetary gearbox reduces backlash and delivers fine control for small linear adjustments. Compact and robust: Metal construction and a compact form factor make it suitable for tight builds and regular use. Simple electrical interface: 2phase, 4wire stepping electronic starter design matches standard twophase stepper wiring for straightforward connection and control. Built for linear motion projects: The integrated linear screw and metal slider convert rotary stepping motion into smooth linear travel for camera sliders, focus rails, and other microactuators. Main features and attributes Gearbox type: Precision planetary gearbox, 5mm sizing for compact drives and tight tolerances. Motor/control type: 2phase, 4wire stepping electronic starter (stepping electronic starter) — designed for stepper operation. Linear mechanism: Screwdriven linear slider with metal slider for durable, lowwear motion conversion. Material: Metal components for gearbox and slider for durability and consistent performance. Functionality: Converts stepper rotary motion into controlled linear movement with improved torque/precision from the planetary gearing. Compatibility: Intended for systems that use 2phase, 4wire stepper interfaces and common stepper drivers/controllers. How this product solves problems Eliminates jitter and backlash common in simple belt or rack setups by using a precision planetary gearbox that tightens gear engagement for finer control. Offers a small, integrated linear solution so you don't need to assemble separate gearbox, leadscrew, and slider hardware — saving space and assembly time. Provides a durable metal sliding interface for longer life in repeatable camera positioning and small automation tasks. Typical applications DIY camera slider and focus rails: Smooth, controllable linear travel for timelapse rigs, focus stacking, or precise framing adjustments. Small automation and robotics: Microactuation, position control, or linear staging where compact size and metal durability are required. Prototype motion systems: Rapidly assemble repeatable linear movement for testing or hobby projects that use 2phase, 4wire stepper control. What to expect in use Accurate smallstep movement suited to camera and small automation needs when driven by a compatible stepper controller. Robust mechanical interface from metal components and a precision planetary gearbox to reduce play and maintain alignment over repeated cycles. Straightforward wiring and setup for users familiar with 2phase, 4wire stepping motor systems; ideal for DIYers and builders. Notes for purchasers Verify the 2phase, 4wire stepping interface matches your driver/controller before installation.
