Introduction:

The 129-402VNV-Q01 is a model from NTC thermistors, which are temperature sensors designed to provide accurate temperature readings. A thermistor is a type of electronic component made up of a combination of two materials – a ceramic material and an electrical conductor – that create a single junction. This junction creates a temperature-dependent voltage signal that can be used to measure temperature.

Application Field:

The 129-402VNV-Q01 is mainly used as a temperature sensor in a variety of fields. It is used in medical equipment, industrial process control, automotive components, and consumer electronics. It is also used in temperature monitoring systems, which are used to measure and control temperatures in manufacturing and industrial plants.

working principle:

The 129-402VNV-Q01 is a NTC (Negative Temperature Coefficient) thermistor, meaning that the resistance of the thermistor decreases with increasing temperature. This means that as the temperature rises, the resistance of the thermistor decreases, allowing more current to flow through the circuit. This change in current is then measured using the output voltage.The 129-402VNV-Q01 is a thermistor with a valence band gap of 3.1 eV, which means that it is sensitive to temperatures of up to 400°C. The thermistor also has a low thermal time constant, which means that it can accurately measure temperature changes quickly.

Conclusion:

The 129-402VNV-Q01 is an NTC thermistor temperature sensor, which is designed to accurately measure temperatures up to 400°C. It is mainly used as a temperature sensor in medical equipment, industrial process control, automotive components, consumer electronics, and temperature monitoring systems. The thermistor works by creating a temperature-dependent voltage signal, which is then measured using the output voltage.
