Pin Assignment Of The Sensor Connector - THORLABS PM100USB Operation Manual

9.2 Pin Assignment of the Sensor Connector

The PM100USB is capable to support custom made detectors. Please read carefully the follow-
ing instruction prior to connecting a self made sensor.
pin connection
3 AGND (analog ground): photodiode ground (anode), thermal and pyro sensor
ground
4 photodiode cathode
5 pyroelectric sensor +
8 thermal sensor +
7 PRESENT: Connect this pin via a 1kΩ – 10kΩ resistor to pin 3 (AGND) to enable
a custom sensor
1 +5V (max. current 50mA from this pin)
6 DGND (digital ground)
9 n.c.
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 PM100USB.
