SERVOMOTOR
PTC 111-K13-140 thermistor
The FKM1 servomotor series has a PTC 111-K13-140 thermistor for the
thermal protection of the servomotor winding. This is the positive
temperature coefficient (PTC) and has no polarity.
The following figure shows the resistance of the sensor as a function of
the ambient temperature (average values):
