6 Cables and Connectors
6.1 Sensor connector
The sensor connector is a 12-pin male (plug) circular bayonet type connector (water proof
I P67, series LF10WBRB-12PD, manufacturer Hirose, Japan). A female counterpart (socket),
e.g. LF10WBP-12S, is used to connect to the sensor. The pin numbering of the socket is shown
in Figure 6-1 the pin description is given in Table 6-1.

Please note that in the standard configuration the sensor has 120 Ohms resistor on board (CAN
bus termination between CAN_L and CAN_H).
For the RS485 data interface there is a 120 Ohms resistor on board of the sensor.
A number of cable sets for initial operation and test purposes are offered by Smartmicro, to
deliver a fast set-up of a sensor system. Among those preconfigured ready-to-run cables as
well as cable stumps (pig tail cables or various lengths) which carry the connector on one side
and open wires on the other.
