AdvertisementAmphenol Advanced Sensors’ Thermometrics RTS ring‑terminal temperature sensors make surface temperature sensing straightforward and robust. Each RTS integrates an NTC thermistor that is electrically isolated from the eyelet, allowing a secure screw‑down attachment to bus bars, battery packs, heat sinks or panel enclosures while maintaining measurement integrity.

To match common hardware, the series offers eyelet sizes for M3, M3.5, M4, M5 and M6 screws and multiple lead lengths. Typical options span 5kΩ to 100kΩ at 25°C with tight resistance tolerances, enabling accurate monitoring across applications from EV/HEV thermal management to industrial power electronics.

The epoxy‑coated sensing element, tin‑plated copper ring terminal and XLPE‑insulated leads are designed for durability, while 1kV dielectric withstand between leads and eyelet enhances safety. RTS devices deliver a fast ~7s response and operate from −40°C to +125°C, covering cold‑start conditions through elevated under‑hood or enclosure temperatures.

With straightforward mounting and proven NTC behavior, they are an easy upgrade over ad‑hoc probes when you need repeatable placement and serviceability. Select the value and format that fits your design and source at Mouser to streamline builds and maintenance.
