1、The thermistor has high sensitivity and can detect temperature changes from ‑40 to 300℃. 2、The thermistor is a glass glaze film resistor, which has moisture resistance, high and low temperature resistance, and good stability. 3、The end of the resistor is a small‑sized glass bead shape, which is small in size and can sense the temperature of the narrow parts. 4、The thermistor wiring surface has a PTFE insulating layer, which is resistant to high temperatures and has low heat absorption. 5、The resistor has high reliability, can work stably for a long time, and is suitable for heating bed or extruder of 3D printer. 1 x Thermistor Item Type: ThermistorMaterial: Glass glaze filmApplication: Heating bed or extruder for Reprap Prusa I3 3D printerResistance value at 25℃=100KThermistor: Approx. 1.25 x 2.0mm / 0.05 x 0.08in small glass beadsWire Length: Approx. 1m / 3.3ftWire Insulation: High temperature PTFEWith a 2-pin female connectorAccuracy: ±1%
