Automobile Air Conditioner Thermistor TPE Temperature Sensor 2.2k Ohm 3950
Description Of The Automobile Air Conditioner Thermistor TPE Temperature Sensor
It is usually installed in the temperature sensor package, which
can also be said to be an evaporator temperature sensor. When the
temperature drops to a certain level, the compressor needs to be
shut down, otherwise it will be frosted and eventually form an ice
block.
Features Of The Automobile Air Conditioner Thermistor TPE Temperature Sensor
Application description】Measure the temperature change of air
conditioner;
[Assembly method] Φ diameter hole locking or wire harness fixing.
● The assembly method is simple and firm.
● The product has good moisture and water resistance.
● The resistance value and B value can be determined according to
customer needs.
