What It Is
This is a 10K Thermistor, specifically a thermistor temperature sensor. It features a 1-meter waterproof probe wire for reliable operation in various environments. The sensor is equipped with an XH2.54 connector for easy integration into electronic systems. Thermistors are resistors whose resistance changes significantly with temperature. This particular model has a resistance of 10K Ohm and a B-Constant of 3950K, indicating its specific temperature-resistance characteristics. It uses a thin film probe type for accurate temperature readings.
Key Uses & Applications
This thermistor is designed for temperature sensing in applications requiring a waterproof probe and a 1-meter cable length. Its 10K Ohm resistance and 3950K B-Constant make it suitable for monitoring temperatures in water, liquids, or humid environments. The XH2.54 connector allows for straightforward connection to microcontrollers, temperature controllers, or other electronic circuits. Thermistors work by changing their electrical resistance in response to temperature variations, providing a precise way to measure and control heat.
How to Choose
When selecting a thermistor, consider the required resistance, B-Constant, and physical characteristics. This product offers a 10K Ohm resistance and a 3950K B-Constant, which are standard values for many temperature sensing tasks. The 1-meter waterproof probe wire and XH2.54 connector are important if your application involves wet conditions or requires this specific connection type. Ensure the cable length is sufficient for your setup. The thin film probe type offers a compact and responsive sensor.
Grit / Spec Guide
This 10K Thermistor has a resistance of 10K Ohm and a B-Constant of 3950K. The cable length is 1 meter, and it features an XH2.54 connector. It is a thermistor temperature sensor with a thin film probe type. The product is water resistant, making it suitable for use in environments where moisture is present. Understanding how thermistors work is key: as temperature changes, the 10K Ohm resistance will vary predictably according to the 3950K B-Constant, allowing for accurate temperature measurement.
Care & Safety
Ensure the XH2.54 connector is properly secured to prevent intermittent readings or damage. While the probe wire is waterproof, avoid excessive bending or sharp crimps that could compromise its integrity. No battery is included or required for this thermistor. Handle the thin film probe with care to prevent physical damage. When installing, ensure the 1-meter cable length is routed safely and not subjected to strain or abrasion. Thermistors work by sensing temperature, so accurate placement is crucial for correct readings.

Resistance Tolerance: ±1%. Thermal Time Constant: Typically 10 seconds (in still air). Q: What do the '10K' and '3950K' values mean for this temperature sensor? A: The '10K' refers to the sensor's resistance of 10,000 ohms at a standard temperature of 25°C (77°F). The '3950K' is its B-value constant, which is a number you'll need for your code to accurately convert the resistance reading into a temperature.. Q: How waterproof is the probe? Can I submerge it in liquid to measure temperature? A: Yes, the sensor itself is housed inside a stainless steel tube and fully sealed with waterproof epoxy. This design allows you to submerge the metal probe tip directly into water or other non-corrosive liquids.. Q: What is the XH2.54 terminal on the end of the wire used for? A: That is a common 2-pin connector that allows for a simple plug-in connection on many electronics boards. If your project doesn't have a matching port, you can just cut the connector off and use the bare wires.. Q: Why would I choose this NTC thermistor instead of a digital sensor like the DS18B20? A: A thermistor is a simple analog sensor, which can be faster to read and uses fewer microcontroller resources than a digital one-wire sensor. They are very responsive to temperature changes and their simple two-wire setup makes them easy to integrate into many different projects.. Q: My temperature readings seem to be off by a few degrees. Is the sensor faulty? A: This is often caused by the formula used in your code. Make sure you are using the correct B-value (3950) and nominal resistance (10K at 25°C) in your calculations. If you've checked your math and the readings are still inaccurate, let us know and we'll help you out..
