4.3 Pin Assignment of the Sensor Connector
The sensor connector allows the access of all Thorlabs “C-type" thermal power sensors. The
power meter interface uses the sensor calibration data, stored in the sensor connector, to cal-
culate the corresponding actual power levels.
Additionally, the PM102x is capable to support custom made detectors. Please read the follow-
ing instruction prior to connecting a self made sensor.
Note:
The PM102 features an amplifier after each Thermal Sensor Input port TH1, TH2, TH3, and
TH4 (Pins 4, 5, 8, and 9). All 4 amplifiers are always on the same range.
Warning
Pin 2 is uniquely used for the EEPROM Digital I/O (memory in Thorlabs sensor heads) and
MUST NOT be used. Connecting this Pin may cause malfunction of the PM102x.
