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 -S92 indicates single male connector; suffix -ST39 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.
▪
The 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.
o
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.
