M12 connectors are key Ethernet cabling compo
nents number onboard subsystems.
HARTING supplies all the connectors and inter-car
cabling between the trains these projects.33 0. Power supplied from a
110/24 DC/DC converter.
The connectors are easy assemble, and they were
designed specifically meet market-specific customer
needs. Activation signals from the emergency brake
handles are sent the onboard systems over the Eth
ernet using unm anaged HARTING eCon 7050 Ethernet
switches and M12 connectors. pivoting threaded hose
connection used accommodate the dynam ics of
the application.
Interference must avoided between the power and
signal lines which are routed very close each other. Frames from analog
cam eras inside the train are routed through digital
video encoders and the Ethernet network the digital
recorders.
