B3950 10K NTC Thermistor Temperature Sensor 5×25mm with XH2.54 Connector and 2-Meter Cable

The B3950 10K NTC Thermistor Temperature Sensor is a highly accurate and waterproof sensor designed for use in a wide range of applications including 3D printers, battery packs, HVAC systems, and other temperature-critical electronics. With a stainless steel 5×25mm probe and a durable 2-meter cable ending in an XH2.54 connector, this sensor is ready to plug and play in embedded and industrial setups.

NTC (Negative Temperature Coefficient) thermistors like this one decrease in resistance as temperature increases, offering a predictable change in signal that is ideal for analog temperature monitoring. The B3950 curve offers high sensitivity and precision at 10KΩ resistance at 25°C, making it one of the most widely used configurations in engineering environments. The waterproof stainless steel enclosure makes it suitable for submersible and outdoor use.
