Core Features

Automotive-grade reliability : Compliant with the AEC-Q100 standard, it operates over a temperature range of –40°C to +150°C and can withstand vehicle‑environment vibrations, humidity, and electromagnetic interference, delivering excellent long-term operational stability.
Fast response and high precision It employs a high-sensitivity NTC thermistor, and its surface-mount design significantly shortens the thermal conduction path, resulting in a rapid response time. Measurement accuracy reaches ±0.5°C, providing reliable data support for vehicle temperature control systems.
Flexible Adaptation Design : The stainless steel mounting base features built-in mounting holes, making it compatible with a wide range of installation scenarios. Cable length, probe specifications, and output signal types can be customized to meet the integration requirements of various vehicle models and components.
Durability and Safety The cable uses automotive-grade sheathing material that is oil-resistant and flame-retardant, offering excellent resistance to aging and corrosion, as well as superior insulation performance, thereby meeting the safety standards of in-vehicle electronic systems.

Typical application scenarios

Temperature monitoring for new energy vehicle battery packs, motor controllers, and DC-DC modules.
Engine/transmission oil temperature and coolant temperature acquisition
Vehicle air conditioning and thermal management system temperature control
Surface temperature measurement of automotive electronic control units (ECUs) and power devices
