从China供应商批发进口12 Volt Photocell Infrared Beam Sensor — FOB条款
Sourcing 12 Volt Photocell Infrared Beam Sensor from Shenzhen Yaoertai Technology Development Co.; Ltd. - China Import Guide
Before placing an order for the 12-volt infrared beam sensor from Shenzhen Yaoertai, verify the exact beam detection range and alignment tolerance for your specific doorway or gate width. The listed range reduction in poor weather is a critical factor for security applications, so request performance data under simulated conditions if possible. Also confirm the relay output's compatibility with your existing control board voltage and current requirements.
Discuss logistics and trade terms directly with the supplier. As they are based in Shenzhen, a major manufacturing hub, shipping options via sea or air freight are typically available. Confirm the minimum order quantity, unit price for your volume, and the standard packaging to ensure the sensors are protected during transit. Lead times for production and shipment are not listed and must be negotiated.
For quality assurance, request a sample unit to test the actual detection performance, power consumption, and build quality before committing to a bulk order. Check the IP55 rating claim by examining the housing seals. Since the supplier's response metrics are currently unavailable, establish a clear communication channel and agree on inspection protocols, such as a pre-shipment quality check, to mitigate sourcing risk.
