How to Choose the Right Connector Manufacturer for Your Project
OEM vs ODM: Which Model Fits Your Needs?
OEM suits standard builds, but custom infrastructure needs ODM flexibility. Working with factory-direct partners like Haiyan allows for custom prototypes that may be available in 7–15 days, depending on the project requirements, while production lead times may vary by tooling and order volume. to meet unique application drawings.
Certification Requirements by Market
For terminal blocks used with copper conductors, verify compliance with the applicable requirements of IEC 60947-7-1 and the manufacturer’s declared ratings. Compliance ensures global safety and regulatory approval for industrial installations.
Total Cost of Ownership: Beyond Unit Price
Cheap connectors often fail under thermal load. Reliable manufacturers provide test reports for insulation resistance, torque, and tensile strength to prevent field failures and lower commissioning risks.
Supply Chain Reliability and Lead Times
Specialized or custom connector orders can require longer lead times depending on product availability, tooling, and order volume. Tier-1 brands often have lead times of 8–14 weeks. Sourcing directly from agile factories can reduce delivery timelines to 20–25 days for mixed-model orders while maintaining high technical performance.
