Fitment: For 3D printers, 3 pieces NTC100K thermistor sensors with a temperature sensor with cable, 3950 brass head, SM terminal. Precise thermal monitoring: This thermistor delivers reliable temperature detection to support consistent heat management during printing and helps maintain stable operation throughout the build process. Supports error printing: Acts as a dependable temperature sensor probe to reduce issues like overheating or inconsistent extrusion, enabling better control over the heating cycle for more reliable prints and cleaner results. Consistent performance over time: The 3D printer thermal detector remains accurate through long sessions and repeated use, quickly adjusting to temperature changes to stabilise performance and minimise failed prints. Specifications and compatibility: Includes 3 NTC100K thermistors with 3950 beta value, brass head, SM terminal, and cable. Designed for printers that use NTC100K sensors with SM terminal connectors. Use scenarios: 1) Replacing worn thermistors in hotend assemblies for reliable temperature sensing. 2) Upgrading multinozzle or dualextruder printers to maintain accurate readings for each nozzle. 3) Keeping a spare parts kit on hand for maintenance and quick replacements during printer servicing.
