Bondtech HeatLink 300°C Thermistor Plug and Play SeMitec Sensor with Molex MicroFit

• Bondtech HeatLink 300°C Thermistor is a precision plug-and-play temperature sensor built for reliable, repeatable readings in demanding 3D printer hotend setups.
• Using the proven SeMitec 104NT-4 sensing element, it helps your firmware maintain stable hotend temperatures—supporting consistent extrusion, cleaner surfaces, and stronger layer bonding across a wide range of filaments.
• This thermistor comes fully assembled in a Ø3 mm × 15 mm stainless-steel cartridge, crimped and laser marked for easy identification. The rugged cartridge protects the sensor from mechanical stress while improving thermal response when installed in the heater block.
• For clean installation, it includes 1.5 m factory-terminated leads protected with a blue sleeve and finished with a Molex Micro‑Fit 3.0 female connector—so there’s no soldering or crimping. To connect it to your printer, select a compatible Bondtech HeatLink interface cable that matches your control board for a true plug-and-play upgrade.
