Core Features

High temperature resistance and high reliability : Utilizing fiberglass‑braided insulated cables, this product offers excellent high‑temperature resistance, flame retardancy, and insulation performance. It can withstand the high‑temperature conditions found in automotive environments and maintains stable performance over long-term operation without aging or embrittlement, making it well suited for high‑temperature applications such as the engine compartment.
Fast response and high precision : Equipped with a built-in high-sensitivity NTC chip and an exceptionally thermally conductive stainless-steel cylindrical probe, it significantly shortens the heat‑transfer path, enabling rapid temperature response. With measurement accuracy up to ±0.5°C, it provides reliable data support for the temperature‑control systems of high‑temperature components.
Compact cylindrical design : The miniaturized cylindrical probe is designed for installation in tight automotive spaces, enabling easy integration into high-temperature components such as the engine compartment, exhaust system, and heating modules, with flexible and convenient mounting.
Environmental resistance and anti-interference The overall structure is made of high- and low-temperature‑resistant, aging‑proof materials, capable of withstanding vehicle‑environment vibrations, oil contamination, and electromagnetic interference. It ensures stable long-term operation and meets the stringent performance standards of automotive electronics.
