With the discontinuation of the KTY 84 / 83 from NXP, the PTC-600 can be an alternative under certain conditions.

With the discontinuation of the KTY 84 / 83 from NXP, the PTC-600 can be an alternative under certain conditions. However, it is not a fully 100% substitute due to its technical and mechanical properties.

Let’s discuss the tailored solution we can develop together with you.

From approx. 160 °C, the incline of the characteristic curve is no longer linear(disadvantage compared to KTY84)
Measuring range up to a maximum of 190 °C (disadvantage compared to KTY84)
Recommended measuring current 1 mA (corresponds to KTY84)
The dimensions of the sensor differ from the KTY sensor: larger outer diameter, longer length, thicker wire
The temperature sensor is polarity-independent (advantage compared to KTY84)
