5.1 Pin Sensor Connectors
The sensor connector allows the access of all Thorlabs “C-type" photodiode, thermal, and pyroelectric
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 PM5020 is capable to support custom made detectors. Please read the following instruc-
tion prior to connecting a self made sensor.
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 PM5020.
