SSI PROTOCOL TIMING DIAGRAM

This oscillogram shows a standard SSI transmission.

Channel 1 reads the clock signal "Clock (+)"

Channel 2 reads the binary code "Data (+)"

The interval between two transmissions (Monoflop time) is 16 microseconds. This performance corresponds to Temposonics V series sensors.

As a result, our sensors are compatible with all controllers currently available on the market.**
