Wiring
Bus cable, cable length and size
To connect the equipment use the supplied M2 connecting sockets.
Note that screened multi-cored twisted-pair control cable
is required as Bus line,
e. g. UNITRONIC ® BUS CAN 2 x 2 x ...mm² or RE-2YCYV-fl 2 x 2 x ...mm².
Control cable assemblies (cable with plug and connector) of various lengths are available as add-on
equipment.
The cable length dictates the baud rate (data transfer rate) between the bus nodes, and the total power
consumption of the sensor dictates the conductor size.
Baud rate Cable length
Number of pairs
and conductor size [mm²]
250 kBit/s 25 m 2 x 2 x 0.34
25 kBit/s 250 m 2 x 2 x 0.5
00 kBit/s 335 m 2 x 2 x 0.75
50 kBit/s 500 m
available on demand
(depends on bus configuration)
20 kBit/s 000 m
0 kBit/s 000 m
Wiring the connecting sockets
Wire the connecting sockets in accordance with the wiring diagram.
