Optimized Configuration & B2B Performance Advantages

  • Multi-voltage compliance: Compatible with DC 2.8 V, 5 V, 12 V, and 24 V systems for flexible B2B integration across global industrial electronics platforms.
  • Precise positioning control: Selectable step angle configurations of 7.5° and 15° integrated with optional 3–12 ppr encoders ensure consistent physical indexing.
  • Optimized structural stability: Delivering balanced holding torque up to 150 mN·m to support exact positional load holding under continuous industrial application cycles.
  • Durable insulation architecture: Internal coils feature Class E insulation ratings and a high threshold of 50 MΩ resistance to prevent failure in high-duty operations.
  • Tailored integration interface: Flexible output shaft options with custom D-cuts, wire lengths, and terminal compatibility (JST/Molex) minimize secondary processing costs.
