从China供应商批发进口433mhz Fixed Code Dip Switch Rf Remote Control — FOB条款
Sourcing 433MHz Fixed Code DIP Switch RF Remote Control from Shenzhen Yaoertai Technology Development Co.; Ltd. - China Import Guide
Before ordering, verify that the remote’s operating frequency matches your receiver’s specifications, as mismatches will prevent functionality. Confirm whether fixed code, learning code, or hopping code is required for your system, as these are not interchangeable without compatible hardware. Request the exact chipset model used in the remote to ensure seamless integration with existing equipment.
Discuss logistics details such as lead time, which can vary based on customisation needs, and packaging options for bulk shipments. Clarify Incoterms, with FOB Shenzhen being the most common for this origin, and agree on payment terms such as TT or LC. Sea freight is typical for large orders, while air freight may be preferred for urgent, smaller batches.
Conduct quality checks by testing a sample unit’s transmission distance and signal stability in your intended environment. Inspect the casing for durability, especially if the remote will be used outdoors. Request documentation such as CE or RoHS certificates if required for your market, and ensure the supplier can provide test reports for frequency stability and power output.
