Hollow-Core Coils for Elevator Clutches are precision-wound electromagnetic coils designed for elevator clutch and brake-related actuation systems. These coils generate a stable magnetic field to support reliable clutch engagement and release, making them suitable for elevator door mechanisms, control modules, and other electromechanical assemblies that require consistent performance and safe operation.

WIRESUN manufactures custom hollow-core clutch coils according to customer drawings, samples, or electrical specifications. Coil dimensions, wire material, winding turns, resistance, inductance, insulation grade, and tolerance can all be customized to match specific elevator system requirements. With CNC precision winding equipment, controlled wire tension, and batch-level inspection, WIRESUN supports prototype development, sample validation, and mass production for OEM/ODM elevator component projects.

Our standard MOQ is 500 pcs for most coil types. For first-time customers or prototype evaluation, we accept small trial orders of 10-50 pcs. MOQ may vary by product complexity. Contact us for a specific quote.

Yes. Samples are available within 5-7 business days after engineering confirmation. A nominal sample fee applies, which is credited toward your first mass production order.

You can email drawings such as PDF, DWG, or STEP files, or fill out our inquiry form. If you do not have drawings, a written description or physical sample is also acceptable.

We can wind wire as fine as 0.01mm using Zongheng CNC precision winding machines with automated tension control.

Yes. Our special-shaped coil series handles non-circular and irregular geometries. Submit your drawings and our engineering team will assess feasibility.

Standard options include bare copper wire, enameled copper wire, and Litz wire. Custom alloy or coated wire options are available on request.

Yes. Provide your target inductance, frequency, and DC resistance requirements, and we will calculate and wind to specification.

WIRESUN is ISO 9001 certified. Products can ship with test reports and COA. Third-party inspection can be arranged upon request.

All coils are wound on CNC machines with precision control. Each production batch undergoes electrical testing, including inductance, DCR, and impedance checks.

Standard documentation includes packing list, commercial invoice, Certificate of Analysis, and electrical test report. RoHS/REACH documents are available upon request.

We ship worldwide. Regular destinations include Southeast Asia, Europe, the Americas, the Middle East, and Russia. Express and sea freight options are available.

Standard terms are 30% T/T deposit upon order confirmation and 70% balance before shipment. L/C is accepted for larger orders, and Western Union is available for sample fees.

Standard products usually take 15-20 business days. Complex custom coils generally take 20-30 business days. Final lead time is confirmed at quotation stage.
