M18x1.5 flange (standard) for bottom electronics connection

* The zero position is specified when ordering the sensor and can be set at a distance of 30 mm or 50 mm

* Non-magnetic spacer No. 1 is required only when the zero position is set at 30 mm from the linear position sensor flange and the sensor sleeve is made of magnetic material.

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.**
