M12 crimp connectors designed market-specific
custom needs
In addition Ethernet switches, HARTING M12 con
nectors with crimp contacts are used board trains. M12 connectors are key Ethernet cabling compo
nents number onboard subsystems. some cases, top-entry upper
housings are used which mate with lower housings that
are mounted existing angle plates optimize cable
routing. HARTING supplies the cabling for Ethernet
backbone that combines CCTV and automatic passen
ger counting systems metro and regional trains. These M12
connectors with crimp contacts have extremely low
profile.
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.

The connectors are easy assemble, and they were
designed specifically meet market-specific customer

HARTING’s expertise seamless cabling systems ex
tends well beyond the company’s broad Ethernet switch
portfolio.
Panel feed-throughs and adapters for use and around
control cabinets are also available. They
can quickly assembled site using standard tools.
HARTING supplies all the connectors and inter-car
cabling between the trains these projects. Power supplied from a
110/24 DC/DC converter. pivoting threaded hose
connection used accommodate the dynam ics of
the application. 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.
Han-Modular®, Han Quintax® and Han® EEE inserts
