Is your 3D printer throwing Thermal Runaway, MINTEMP, or MAXTEMP errors? A damaged or fluctuating thermistor is the most common culprit. Our NTC 100K 3950 Thermistor features high-quality glass bead sensors protected by rugged Teflon (PTFE) tubing. Unlike cheap version sensors wrapped in basic plastic that melts over time, this premium lead wire easily withstands constant operational temperatures up to 300C, ensuring safe, accurate, and ultra-stable temperature feedback to your printers mainboard.
Universal Firmware Support: Pre-configured as Sensor Type 1 in Marlin and EPCOS 100K B57560G104F in most slicer/printer configurations.
Premium Teflon Insulation: Heavy-duty PTFE sleeving prevents the bare copper wires from shorting out against the metal hotend block.
1-Meter Long Lead: Generous cable length allows for neat cable routing from the print head through the cable sleeve all the way back to the mainboard.
Highly Responsive: Tiny glass bead form factor reacts instantly to fractional temperature changes, allowing your PID tuning to maintain stable temps.
