FAQ
Is the harness universal?
Wiring harnesses are usually not universal, and their design needs to be customized according to specific product requirements. Different devices in the model specifications, functional configuration and application scenarios and other aspects of the differentiated needs, will directly affect the design of the harness.
What are the certification credentials for your harnesses?
Our wiring harnesses are certified by the industry IATF16949, environmentally friendly in accordance with RoHS/REACH standards, and are manufactured to do salt spray testing to meet the indicators before shipping and applying to PCB boards.
What are the rating tests for your harnesses?
Specifically depends on the demand and application scenarios, we often do the level of testing, such as: multi-bending scenarios applied to the flexibility test, IP67 waterproof test, high temperature 150 ℃ test, flame retardant grade UL VW-1 test, and so on.

What about shipping?
For small parcels, we recommend using an express courier (e.g. DHL, UPS, FedEx and EMS door-to-door services!) This is the fastest but also the most expensive way. For large parcels, sea freight is the best solution. We can only give you accurate shipping costs if we know the details of the quantity, weight and shipping method.
