User Manual - QG65N2 SAE J1939 Inclinometer (Type JB) V1.1
4.3.
Connection
The sensor is equipped with either a single 5-pole M12 (A-coded) male connector according to IEC 61076-2-101, or
with an additional 5-pole M12 (A-coded) female connector. This is specified in the suffix of the device model
designation: suffix CM indicates single male connector; suffix CFM indicates both a female and a male connector.
The advantage of two connectors is that devices can be daisy-chained in the CAN network. The voltage supply is
forwarded from the male to the female connector, providing both power and bus-connection to the next sensor
with a single cable harness. The connection between male and female connector acts as an internal T-junction.
The pin assignment is according to CiA 303-1 V1.8.0.

•
The maximum current for the internal T-junction is 2.5 A. This must be taken into account when using daisy-chained
connections.
•
The voltage supply must be dimensioned to prevent exceeding the specified voltage limits.
•
The power consumption is about 50mA typical.
•
This device must be connected to a class 2 power supply.
•
Connect the sensor only to an approved CAN controller which must have a grounded shield. Alternative: connect the
sensor housing to a grounded shield. All mentioned EMC standards that are met (see Declaration of Conformity)
have been done with the housing connected to a grounded shield.
Installation of wiring and the opening and closing of electrical connections must only be carried out
in de-energized
state!
Short-circuits, voltage spikes, etc. can cause malfunctions and/or cause the installation to become uncontrolled,
creating a serious risk of
injury or damage to property.
