Amphenol Advanced Sensors' ring temperature sensors provide accurate and dependable surface temperature measurement across a wide temperature range

Image of Amphenol Advanced Sensors' RTS Series of Ring Terminal Temperature SensorsAmphenol Advanced Sensors thermometrics RTS series of ring-terminal temperature sensors are ideal for surface-temperature measurement applications. The ring terminal sensors incorporate a negative temperature coefficient (NTC) thermistor with two 28 AWG XLPE-insulated tin-plated copper lead wires mounted inside the barrel of an M3, M3.5, M4, M5, or M6 eyelet/ring terminal. The eyelet/ring terminal provides easy mounting and the XLPE insulated cable completes the rugged construction of the sensor. These sensors provide accurate and dependable surface temperature measurements across a wide temperature range.
