8mm 2Phase 4Wire Stepping Electronic Starter — Linear Slider Screw Shaft Moving Block, 10mm Stroke Compact, precise linear motion for DIY camera and small automation projects. This 8mm stepper electronic starter combines a 2phase 4wire stepping configuration with a screwdriven linear slider moving block that delivers controlled travel over a 10mm stroke. It is designed for applications that require shortrange, repeatable positioning in a small footprint. Key benefits Precise shortrange positioning: Screwdriven moving block converts step motion into smooth linear travel across a 10mm stroke for fine adjustments. Spacesaving 8mm form factor: Compact shaft and slider fit into tight camera rigs and small mechanical assemblies. Simple stepping control: 2phase 4wire stepping configuration supports standard stepper control methods for accurate micropositioning. Ideal for DIY camera projects: Suited for lens focus rails, microslides, and compact timelapse or macro setups where small, repeatable movements are required. Primary attributes Size: 8mm shaft/assembly (compact design) Motion type: Linear slider with screw shaft moving block Stroke: 10mm total travel Electrical configuration: 2phase, 4wire stepping electronic starter Purpose: Designed for DIY camera and small linear motion applications Typical applications Macro and focus rails: Precise 10mm travel for fine lens focusing and repeatable focus stacking on camera rigs. Compact timelapse or motioncontrol rigs: Small linear adjustments for controlled camera movement or lens shifts in tight assemblies. Miniature stages and small robotics: Shorttravel positioning for sensor alignment, microactuation, or precision adjustments in compact mechanisms. Installation and use notes Designed for integration into DIY camera builds and smallmotion mechanisms; mount and align the slider to your rig to achieve smooth linear movement. The 2phase 4wire configuration requires a compatible stepper control method appropriate to your project. Use within the 10mm stroke range to maintain repeatability and expected mechanical behavior. This 8mm stepping electronic starter with screwdriven linear slider and 10mm stroke offers a compact, accurate solution for projects that need small, repeatable linear motion without a large mechanical footprint.
