Wiring

Bus cable, cable length and size

To connect the equipment use the supplied M12 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.
