This set provides the convenience of a hot swappable lead cable, allowing you to replace the thermistor at the hotend via its JST-SM interface.
NTC 100k B3950 thermistors provide a good balance between accuracy and sensitivity, making them suitable for temperature measurements in 3D printing applications. Their resistance changes in a reasonably linear manner with temperature, allowing for precise temperature control.
NTC 100k B3950 Thermistors are one of the most common thermistors used in 3D Printers, including Creality 3D printers etc.
