Ring Terminal Temperature Sensor

Ring Terminal Temperature Sensors are commonly used in the automotive and industrial markets allowing surface temperature measurement with designs and performance tailored to specific application requirements. The sensors consist of an NTC thermistor located within a ring-terminal, which is screw-fixed into position. Lead wires and connector systems provide a means of monitoring the temperature at a remote control board.
