WTF083B001

CTS Coolant Temperature Sensor The Coolant Temperature Sensor (CTS) monitors the temperature of the coolant that is being pumped around the battery to cool the battery module of EV/PHEVs. If the battery module starts to overheat, the Coolant Temperature Sensor relays a signal to the Battery Management System (BMS). The BMS uses this information to prevent battery packs from any damage and maximize the performance. Applications Features • Battery coolant temperature • IP67 rated package • HVAC refrigerant lines • Compact IP67 design with integrated connector • P/No : WTF083B001 • Customizable to meet application installation needs • Variety of RvT curves and terminal plating available • Operating temperatures to 100°C • Fast response proven design Amphenol Advanced Sensors CTS Specifications R vs. T Temp.
