3D Printer Thermistor NTC 3950 100K Temperature Sensor for Hotend and Heated Bed, Precise Control

NTC 3950 100K Temperature Sensors, 5 Pack Key benefits Accurate and reliable temperature readings with +/ 1 Percent accuracy, suitable for precise control and monitoring tasks. Wide operating range from 40 degrees Celsius to 300 degrees Celsius, making these sensors useful for low temperature monitoring and temperature applications. Fast response: thermal time constant 7 s or less gives quicker detection of temperature changes compared to slower sensors. Ready to use: 1.2 m (47.24 inch) cable and a standard 2 pin DuPont connector for easy plug and play connection with many controllers and development boards. Durable construction using plastic and metal components for stable performance and long service life. Pack of 5 sensors provides spares or installation across multiple points for better system control. Why you need this product Get dependable temperature feedback for control loops, data logging, and safety cutoffs with a 100K Ohm NTC 3950 thermistor that is compatible with many common temperature input circuits. Long cable length simplifies routing and placement without the need for extensions. Standard DuPont connector enables fast wiring to common controllers and adapters without soldering or custom connectors. Multiple sensors in one package makes it easy to monitor several locations or keep replacements on hand. Key specifications Type: NTC 3950 thermistor Resistance value: 100K Ohm Accuracy: +/ 1 Percent Temperature coefficient of resistance: approximately 2 to 5 Percent per degree Celsius Operating temperature: 40 degrees Celsius to 300 degrees Celsius Max rated load: 45 mW Hot time constant / Thermal time constant: 7 s maximum Cable length: 1.2 m / 47.24 inches Connector: 2 pin DuPont connector Material: Plastic and metal Color: White Package contents: 5 PCS temperature sensors Typical applications 3D printing: Monitor hotend or heated bed temperature for more stable prints and easier calibration with a compatible controller that accepts 100K NTC inputs. HVAC and temperature controllers: Use in thermostats, environmental chambers, and process control systems where reliable temperature feedback and a long cable are needed. Hobby and laboratory equipment: Ideal for ovens, kilns, reflow stations, and other devices that require sensing up to 300 degrees Celsius or distributed sensing at multiple points. Compatibility and installation notes Designed for systems that accept 100K NTC 3950 thermistor inputs and standard 2 pin DuPont connectors. Verify your controller or readout accepts NTC 3950 characteristics before installation. Observe the max rated load of 45 mW to avoid selfheating errors and maintain measurement accuracy. Place the sensor tip in contact with the measurement surface and allow up to the thermal time constant for stable readings when temperature changes. What is included Five NTC 3950 100K temperature sensors with 1.2 m cables and 2 pin DuPont connectors, ready for immediate integration into compatible systems.
