Rail Traffic

For a perfect


Sensor Line offers a comprehensive range of original parts and accessories to facilitate the installation and increase the performance as well as to ensure a flawless functionality of the fiber optic traffic sensors.

SL XD 1100

The SL XD-1100 is a one-channel static opto-electronic interface for Sensor Line fiber optic rail pad sensors (FORPS). The electronic operates the SL FORPS sensors responding to changes of its optical transmittance. It provides one analogous and one serial output proportional to that response. It samples the signal with 10kHz and has a dynamic range of 33dB. All of our FORPS sensors (FORPS UIC 60/HS, FORPS UIC 54, FORPS S 49) can be directly connected to the XD-1100.
