B3950 10K NTC waterproof High precision thermistor temperature Sensor 5 x 25mm with XH2.54 Connector can be used to measure temperature in a variety of applications.

The sensor has stainless steel 5 x 25mm tip with an XH2.54 connector with a 5-meter cable. It is Negative thermal coefficient (NTC) will decrease. But the formula in practice is not linear,  so sometimes an accurate table of measurements is better than the linear formula. These measurements can usually be found in the datasheet that accompanies the thermistor.

Specifications and Features:

1. Probe sheath material: Stainless Steel
2. Style: B3950 10K
3. Resistance value: 10K ± 1%
4. Measurement range: -20 to 105 °C
5. Cable Length: 3-meter
6. Size of probe: 5 x 25 mm
7. Output wires: 2
8. Typical Dissipation Constant: 5mW/ °C
9. Probe insulation: >100MOhm

Package Includes:

1 x B3950 10K NTC Thermistor Temperature Sensor 5*25mm with XH2.54 Connector with 3-meter Cable

This W3230 AC110-220V Digital Temperature Controller Microcomputer Thermostat Switch features an NTC 10K waterproof temperature sensor.
