6 Cables and connectors
6.1 Sensor connector
The used sensor connector is an 8-pin male circular connector (water proof IP67, series 712,
manufacturer Binder GmbH, Germany). A female counterpart has to be used to connect to
the sensor. The pin numbering of the female connector is shown in Figure 6 the pin out of
the connector is shown in Table 1.

Please note that in the standard configuration the sensor has no 120Ohms resistor on board
(CAN bus termination between CAN_L and CAN_H). The resistor is nevertheless required at
either end of a CAN bus and is in most cases integrated in the cable delivered along with the
sensor (if cable is manufactured by Smartmicro).
