Compact, precise linear motion for camera rigs — this 5mm Gear Stepper Electronic Starter combines a 2phase 4wire stepper motor, a linear screw rod slider and a telescopic bracket designed for digital camera use. It gives repeatable, controllable linear travel for small sliders, focus pulls and other camera positioning tasks. Key benefits Accurate, repeatable positioning: the 2phase 4wire stepper configuration delivers controlled, stepwise motion for precise adjustments. Compact drive interface: the 5mm gear size keeps the assembly small and suitable for lightweight camera setups. Smooth linear actuation: the integrated linear screw rod slider converts rotary motion into straightline travel for reliable, jitter movement. Practical mounting: the telescopic bracket provides a compact, extendable interface for attaching a digital camera or accessory. What this product does and why you need it Provides motorized linear motion in a small form factor for tasks where manual adjustment is slow or inconsistent. Ideal for fine focus adjustments, shortrange camera slides, and other automated camera positioning where precision and repeatability matter. Useful for DIY camera rigs, small timelapse slides, and automated photography accessories that require a compact stepperdriven linear actuator. Key attributes (from product specification) Motor type: 2phase, 4wire stepper motor. Gear size: 5mm gear. Motion mechanism: linear screw rod slider (leadscrew style linear conversion). Mounting: telescopic bracket intended for use with digital cameras. Intended application: digital camera positioning and related camera motion tasks. Typical use cases Timelapse sliding shots: add smooth, repeatable shortrange slides to timelapse sequences to introduce dynamic motion without manual intervention. Motorized focus or macro adjustment: use the linear screw rod slider to perform precise focus pulls or incremental focus stacking where small, accurate movements are required. Small rig automation: integrate the stepperdriven slider into a compact DIY dolly, pan/tilt assembly, or accessory for hands camera positioning. Installation and operation notes The assembly includes a 2phase 4wire stepper motor and the linear screw rod slider with telescopic bracket for mounting a digital camera. Operation requires a compatible stepper driver/controller and an appropriate power source (controller and power not specified in the product title). Mounting and mechanical coupling should be checked for the camera model in use; the 5mm gear and telescopic bracket are sized for compact setups and lightweight cameras or accessories. Practical considerations suited for lightweight digital cameras, compact rigs and accessory automation where a compact stepperdriven linear actuator is needed. Check compatibility with your existing controller, mounting hardware and load requirements before installation.
