Square-terminal NTC temperature sensor

Main Features:

This series of square‑terminal NTC temperature sensors is specifically designed for high‑reliability temperature measurement at critical junctions such as energy‑storage battery busbars, high‑power modules, and busbars. Featuring oversized metal terminals and an insulated encapsulation, the sensor can be securely fastened to the target surface with screws, offering excellent thermal conductivity, robust electrical insulation, and superior resistance to vibration and impact. It provides stable, accurate temperature data to support battery management systems (BMS), making it a core component for thermal control and safety in new‑energy and energy‑storage systems.
