For Existing Product Designs or Samples
If you already have product drawings or physical samples, simply provide them to us, and we can proceed with production.
Custom Product Development (No Existing Reference)
If you need to develop a new product without existing samples or drawings, please provide the following details for our design team to create a tailored solution: a. Electrical Requirements: Operating current and voltage. b. Connector Specifications: Model numbers, samples, or specifications for connectors at both ends of the cable. c. Pin Configuration: Pin-to-pin correspondence for the cable assembly. d. Environmental Conditions: Application scenario (e.g., lawn mowers, mining equipment) and required certifications (oil resistance, waterproofing, high-temperature tolerance, flexing tests, etc.). e. Electrical Testing Requirements: Transmission characteristics, voltage withstand, conduction resistance, insulation resistance, etc.
