By continuously introducing advanced production equipment and modern management systems, we ensure that our products are innovative, durable, and meet the highest industry standards.
Our commitment to quality, reliability, and timely delivery has earned the trust and appreciation of clients worldwide, establishing a footprint that spans Europe, North America, and Southeast Asia.
"Credit First, Customer First, Quality Satisfaction, On-Time Delivery"
We focus on understanding customer needs, promoting environmentally friendly production, continuously improving product quality, and optimizing production processes.
Decoding the complexity of modern thermal management in the era of New Energy Vehicles (NEVs).
As the global automotive industry shifts towards electrification, the demand for high-precision Car Temperature Sensors has surged. Modern vehicles require up to 20 different thermal sensors to monitor everything from cabin air to battery pack electrolytes.
Wenzhou Sedo Auto ensures all sensors meet international OEM specifications. We navigate complex regional regulations including REACH, RoHS, and CE, providing "Zero-Defect" products that guarantee safety in extreme thermal environments.
Beyond component supply, we offer integrated solutions for engine cooling loops, transmission oil temperature monitoring, and high-voltage battery thermal stability for EVs.
Our vertically integrated facility in Wenzhou utilizes state-of-the-art machinery to ensure micron-level precision.

At Wenzhou Sedo Auto Co., Ltd., we are not just following trends; we are creating them. Our R&D team is currently focused on the next generation of NTC (Negative Temperature Coefficient) and PT (Platinum Resistance) sensing technologies.
The future of Car Temperature Sensors lies in the Battery Management System (BMS). We are investing in high-voltage isolated sensors that can safely monitor temperature across hundreds of cells, preventing thermal runaway and extending battery life cycles.
Specially calibrated sensors for Northern European and Canadian markets that maintain accuracy at temperatures as low as -40°C, essential for cold-start reliability.
Enhanced thermal dissipation and UV-resistant connectors designed for high-humidity and high-heat environments like Southeast Asia and the Middle East.
We provide full documentation for local customs, including Certificate of Origin, SGS inspections, and tailored packaging for long-distance maritime transit.
Expert insights into selecting and maintaining automotive temperature sensors.
Looking ahead, Wenzhou Sedo Auto Co., Ltd. aims to strengthen global partnerships, drive innovation in the automotive industry, and create long-term value for customers and society alike, achieving a future of mutual growth and shared success.
