compa bility with ILT1700 (and IL1350) sensors. Future ILT2500 sensors will be supplied with an
internal memory chip inside the D-sub connector that includes the model and serial number of the
sensor as well as calibra on informa on. The ILT2500 will have the ability to read the smart detector
informa on and apply the proper calibra on factor to be used during tes ng.
The D-sub not only receives the current generated by the sensor a er exposure to light, it also
supplies bias to sensors requiring bias for power and/or to improve response me. The D sub
connector is not limited to only measuring devices manufactured by ILT. Any solid state device that
generates current from 50 pA to 1 mA can be connected to the ILT2500 for measurement of current.
