Low Profile Temperature Sensor Low profile sensor for applications in confined spaces. The FL temperature sensor is a small NTC chip sensor enclosed in a flexible PCB that measures surface temperature. It is designed to meet the volume, cost, and delivery expectations of Original Equipment Manufacturers (OEMs). Applications Features • EV / HEV Battery pack cell surface temperature. • High reliability and stability over sensor lifetime. • Low profile applications. • Low profile – 0.5 mm maximum thickness. • Flexible PCB design. • Electrical connection by soldering or edge connection. • Suitable for temperature measurement in rechargeable battery packs. • Low mass NTC thermistor for fast ti me response. • Alternative RvT curves available. • Custom Flexible PCB lengths available. • Suitable for temperature measurement in rechargeable battery packs.
