High Temperature Thermistor HT-NTC100K

High-temperature 100K NTC thermistor for hotend temperature sensing. This HT-NTC100K probe is the high-temp thermistor style used for 3D-printer hotends when a standard glass-bead 100K sensor is not enough.

Why use this instead of a standard thermistor?

• Built for high-temperature hotend work where ordinary 100K NTC sensors are typically limited to lower operating temperatures.
• Metal probe body slides into a heater block thermistor bore for cleaner retention than loose bead-style sensors.
• Two-pin lead makes it a simple replacement sensor for boards configured for a compatible 100K NTC / HT-NTC100K profile.

Specifications

• Sensor type: HT-NTC100K / 100K NTC thermistor
• Application: 3D-printer hotend temperature measurement
• Probe style: metal cartridge-style probe with white lead and black 2-pin connector
• Variants: Single or Pack of Two
• MPN: HT-NTC100K

Use it with

• Replacement hotend heater setups alongside a 24V 40W heater cartridge.
• Higher-output hotend builds alongside the 50W high-temperature heater cartridge.
• If you need a different sensor family, compare against the standard 100K NTC 3950 thermistor or the PT1000 temperature sensor.

Gotchas

• Not a heater cartridge — this reads temperature only.
• Firmware must be configured for the thermistor type you actually install. Match your board, firmware, and hotend requirements before printing high-temperature materials.
• Do not substitute it for a PT100/PT1000 sensor unless your electronics and firmware are configured for that change.
