RTS Ring Terminal Temperature Sensors

Amphenol Advanced Sensors RTS Ring Terminal Temperature Sensors feature an NTC chip thermistor mounted in an eyelet tag for surface mount temperature measurement. Operating within a -40°C to +125°C temperature range, these sensors offer a 7s time response and are available in eyelet configurations to fit M3, M3.5, M4, M5, and M6 screw sizes. Applications include EV/HEV bus bars, battery covers, thermal management, heat sinks, and panel enclosures.
