O-type terminal-mounted NTC temperature sensor

Main Features:

This series comprises O‑type terminal‑mounted NTC temperature sensors specially developed for the automotive electronics sector. Featuring metal tabs with standard mounting holes and an epoxy‑encapsulated design, these sensors incorporate a high‑sensitivity NTC thermistor element. They can be directly secured to the surface of the target component via screws, enabling rapid and accurate temperature measurement, and are widely suited to surface‑temperature‑sensing applications in new‑energy vehicle electronic control units, power devices, and onboard equipment.

Core Features

Excellent thermal conductivity and conformability : The metal ear tabs can closely conform to the component being measured, significantly shortening the thermal conduction path and enabling rapid temperature response. Measurement accuracy reaches ±0.5°C, providing reliable data support for vehicle‑mounted thermal management systems.
Automotive-grade reliability and stability The epoxy‑encapsulated structure offers excellent moisture and oil resistance as well as superior insulation performance. Paired with automotive‑grade cables that withstand extreme temperatures, it can endure the vibrations, temperature fluctuations, and electromagnetic interference typical of in‑vehicle environments, ensuring long‑term stable and reliable operation.
Screw-Fixed Installation Design : O‑type terminals with standard mounting holes can be securely fastened directly with screws, ensuring a robust installation that resists loosening and prevents poor contact, making them well suited for long-term use in high‑vibration automotive environments.
Flexible customization : Ear‑tab dimensions, mounting‑hole specifications, cable lengths, and electrical parameters (resistance values, B‑values) can all be customized to meet the integration requirements of various vehicle models and electronic control systems.

Typical application scenarios

Temperature monitoring of power devices in new-energy vehicle motor controllers and DC-DC modules.
Surface temperature acquisition for vehicle-mounted electronic control units (ECUs) and IGBT modules
Temperature measurement of busbars and terminal blocks in automotive battery management systems (BMS)
Vehicle-mounted charging module and power management system temperature monitoring
