The sensor can be connected at the SubD-25 input connector.
It occupies the position which is usually used for the guard ring bias. So all mesytec cable sets allow to connect the sensor at the detector site between the guard ring pin and analog ground (neighbour pin)
Sensor type: NTC thermistor, Epcos B57861-S502-F40
