Thermistor Sensors
Quickly and accurately check the temperature of electronics and appliances. As the temperature of your device rises, the resistance of these NTC (negative temperature coefficient) sensors decreases. They work best with small temperature changes and temperatures similar to the ambient air. They’re not as accurate as RTD probes for high heat and wide temperature swings.
Pair these sensors with a temperature controller to maintain the ideal temperature of your device.

Current Limiters
Also known as thermistors, these devices are used to protect power supplies, motor drives, and battery chargers from large inrush currents when the equipment is turned on.
