NTC-thermistor in TO-220-pakket voor DIP-printplaatmontage

This sensor is essentially a reed switch, encased in an ABS plastic shell. Normally the reed is 'open' (no connection between the two wires). The other half is a magnet. They're often used to detect when a door or drawer is open, which is why they have mounting tabs and screws.

RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time. An RTD is a passive device. It does not produce an output on its own. External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage. Typically 1 mA or less measuring current, 5 mA maximum without the risk of self-heating.

De miniture NTC-thermistor uit de MF5A-5-serie is gemaakt met epoxyharscoating en isolatiedraad zoals PVC-draad, teflon of Kynar-draad. Het heeft voordelen van miniatuurformaat, hoge precisie en snelle respons.
