9.3.2 Ethernet connection
The sensor can be powered in the following ways:
•
Using connector A
•
Using the PoE (Power over Ethernet) function, which is integrated
into the Ethernet connection on connector B.
To power the unit via PoE, a network switch that supports PoE is
needed. PoE comes into two standards:
•
Type A: The PoE switch powers the device via Pair 2 (Pin 1 and Pin
2) and Pair 3 (Pin3 and Pin6)
•
Type B: The PoE switch powers the device via Pair 1 (Pin 4 and Pin
5) and Pair4 (Pin7 and Pin8)
This sensor supports both types.
Connection cable – M12 X-coded to RJ45
When Modbus TCP is chosen as the sensor output, a 5 m 8-pore cable is
supplied in the delivery package. The cable has the M12 and RJ45 plugs
on the ends. RJ45 is used to connect the sensor to a PoE switch.
