Sensor connector
The used sensor connector is a 12-pin male (plug) circular connector (water proof IP67,
LF10, manufacturer Hirose). A female counterpart (socket), e.g. LF10WBP-12S, has to be
used to connect to the sensor. The pin numbering of the socket is shown in Figure 7 the pin
description is given in Table 2: Sensor connector pin out Model UMRR-0F0002.

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).
For the RS485 data interface there is a 120Ohms resistor on board of the sensor. The RS485
interface is full duplex hardware. Semi-duplex operation is also supported; please refer to the
User Manual.
