Compact, precise linear motion module designed for smallformat projects, especially DIY camera rigs. This 8mm stepper electronic starter combines a 2phase, 4wire stepping drive with a screw shaft moving block to deliver controlled linear travel over a 10mm stroke. It is ideal when you need reliable, repeatable smallrange motion in tight spaces. Why this product solves common problems Precise short travel: The 10mm stroke gives controlled, repeatable linear displacement suitable for fine adjustments such as focus or sensor positioning. Compact footprint: The 8mm form factor and integrated moving block save space compared with larger linear actuators, making it easier to fit into custom camera housings or compact automation assemblies. Simple stepper interface: The 2phase, 4wire stepping arrangement is compatible with standard stepper drivers and common DIY electronics, simplifying integration and control. Key features and attributes Model type: 8mm Stepper Electronic Starter Drive: 2phase, 4wire stepping configuration Motion element: Screw shaft with moving block (linear slider) Stroke length: 10mm total linear travel Primary function: Precise incremental linear motion and positioning Intended use: DIY camera projects and smallscale precision motion applications Benefits at a glance Accurate incremental positioning for repeatable results Compact and integrated solution reduces assembly complexity Straightforward electrical interface for hobbyist and prototype work Suitable for fine adjustments where space and stroke are limited Practical applications and use cases Camera focus/zoom adjustment: Add smooth, repeatable micromovements to manual lenses or small camera modules for precise focus pulling, macro work, or automated focus stacks. Miniature timelapse or slide adjustments: Use as a shortstroke slider in compact timelapse rigs or tabletop sliders that require controlled small displacements. Small automation and prototyping: Integrate into robotics, inspection fixtures, or laboratory devices where fine linear positioning over a 10mm range is required. Integration tips Interface with standard stepper drivers that support 2phase, 4wire steppers. Mount the module where a 10mm linear travel is sufficient; the compact 8mm design is suitable for enclosed or spaceconstrained builds. Use for incremental positioning tasks rather than longtravel applications. This 8mm stepper electronic starter with screw shaft moving block provides a straightforward, compact solution for precise shortrange linear motion, making it a practical choice for DIY camera builders and smallscale motion projects.
