10K B3950 NTC Temperature Sensor ±1% with M4 Stainless Steel Probe
This 10KΩ B3950 NTC temperature sensor is designed for temperature detection and monitoring in household appliances and other electronic equipment. It uses a high-precision NTC thermistor with 10KΩ resistance, B-value 3950, and ±1% resistance tolerance.
The sensor features a stainless steel M4×8 probe housing for direct contact with the measured environment. It is assembled with UL2651 26AWG wire, 160mm cable length, and an XH2.54-2Y connector housing for convenient PCB or control-board connection.
The probe and cable configuration can be customized according to different installation structures and temperature measurement requirements.
How NTC Temperature Sensors Work
An NTC thermistor has a negative temperature coefficient, meaning its electrical resistance decreases as temperature increases.
For a 10K B3950 NTC thermistor, the nominal resistance is 10KΩ at 25°C, while the B-value of 3950K describes the thermistor's resistance-temperature characteristic.
When the sensor is connected to a temperature measurement circuit, the resistance change can be converted into a corresponding temperature reading by the control system.
This makes NTC thermistors suitable for applications where compact size, straightforward electrical integration and temperature monitoring are required.

Frequently Asked Questions
What is a 10K NTC temperature sensor?
A 10K NTC temperature sensor is a thermistor-based temperature sensing component with a nominal resistance of 10K Ω, typically specified at 25°C. Its resistance changes with temperature and can be measured by an electronic control circuit.
What does B3950 mean on an NTC thermistor?
B3950 refers to the thermistor's nominal Beta value of 3950K, which describes its resistance-temperature characteristic. The B-value is an important parameter when selecting an NTC thermistor for a specific temperature measurement circuit.
Can the NTC temperature sensor be customized?
Yes. Resistance, B-value, accuracy, wire length, connector, probe dimensions and other mechanical and electrical parameters can be customized according to application requirements.
Where are 10K B3950 NTC sensors used?
They are commonly used for temperature detection and control in air conditioners, refrigerators, freezers, water heaters, HVAC systems, household appliances and electronic control equipment.
What is the sample lead time?
Standard samples will take 3-7 working days. Customized samples take 7-15 working days.
Do you have any MOQ Limit?
Low MOQ; 1 piece for sample checking is available.
How do you ship the goods, and how long will it take to ship to my country?
We usually ship by DHL, UPS, FedEx, TNT, or by the customer's appointed freight forwarder. It usually takes 3-7 days to arrive.
