High heat-resistant and high-reliability temperature sensor developed for automotive motors.
This is a compact and thin temperature sensor that uses our glass-sealed thermistor (NT thermistor) sealed with fluororesin.
Product Overview
● Features
・Since the entire sensor is covered with fluororesin, it has excellent heat resistance, chemical resistance, and oil resistance.
・The temperature sensing surface is flat, providing good thermal responsiveness to heat sources with flat surfaces, such as flat coils.
