Core Features

High precision and fast response It employs a high-sensitivity NTC thermistor paired with a stainless-steel housing boasting excellent thermal conductivity, significantly shortening the heat‑transfer path to deliver rapid temperature response. Measurement accuracy reaches ±0.5°C, providing precise data support for in‑vehicle temperature control systems.
Automotive-grade reliability Both the housing and the wiring harness are made from high- and low-temperature‑resistant, aging‑proof materials, capable of withstanding vehicle‑environment vibrations, temperature fluctuations, and electromagnetic interference. They ensure stable long-term operation and meet the stringent performance requirements of automotive electronics.
Compact and Easy-to-Install Design : A bullet‑shaped miniaturized probe paired with a custom connector, designed for installation in tight automotive spaces—no complex mounting required, making it easy to integrate into various vehicle‑mounted systems.
Flexible customization : Probe length, cable specifications, connector type, and electrical parameters (resistance value, B‑value) can all be customized to meet the integration requirements of various vehicle models and electronic control systems.

Typical application scenarios

In-vehicle electronic control unit (ECU) and power module temperature monitoring
