Focusens Ring Terminal NTC BMS Temperature Sensor
The Focusens Ring Terminal NTC BMS Temperature Sensor is a precision Negative Temperature Coefficient (NTC) thermistor designed for direct integration into Battery Management Systems (BMS). Featuring a ring terminal for secure, low-resistance connection to battery terminals or busbars, it provides accurate temperature monitoring from -30°C to 120°C, essential for protecting lithium-ion and other battery packs from thermal runaway and optimizing charge cycles.
Features
- 10kΩ ±1% NTC Thermistor with Ring Terminal for direct battery pack attachment
- Wide operating temperature range from -30°C to +120°C
- Low thermal time constant (≤30s) for rapid response to temperature changes
- Maximum power rating of 5mW ensures minimal self-heating for accurate readings
- Essential safety component for BMS in EVs, energy storage, and portable power systems

This sensor utilizes a high-precision NTC thermistor element, where resistance decreases predictably with increasing temperature. The integrated ring terminal provides a robust mechanical and electrical connection directly to battery cell terminals or busbars, minimizing contact resistance and ensuring the sensor accurately reflects the core battery temperature. This direct mounting is critical for reliable thermal management in high-current applications.
Designed specifically for Battery Management Systems, the sensor outputs a variable resistance that the BMS controller’s analog-to-digital converter or dedicated thermistor input can read. Its fast thermal time constant allows the BMS to react swiftly to sudden temperature spikes, enabling proactive measures like current limiting or charging suspension to prevent dangerous conditions such as overheating or thermal runaway.
