rated protection and can endure 1,000 hours of salt
spray resistance. These heavy duty connectors are
built on a modular basis so they can offer power, signal
and data transmission in a single compact unit. A one-
piece connector frame allows for easy assembly of the
modular inserts, and a docking frame that allows for
blind mating provides more savings in installation time
and costs.
TE’s heavy duty connector has a history dating back over
60 years, during which time it has gone through various
generations and options, offering special features for a
wide range of applications. “The heavy duty connector
is an iconic product that stands the test of time,” says
Sascha Lambauer, product manager for TE’s heavy
duty connectors. “Like many other TE solutions, the
HDC also withstands harsh environments, reliably
performing under demanding operating conditions, and
is engineered to give designers flexibility and reliability
in their servo and spindle motor designs.”
Servo motors are increasingly being chosen for their
high efficiency, especially in material handling systems
and inside machinery. Meanwhile, advances in machine
tooling requiring high precision and reliability are leading
to spindle motors being put at the heart of modern
production systems, delivering high quality end products.
Expanded beam fibre optic cable
assembly for connections in the toughest
environments
HARTING has developed an expanded beam fibre optic
connector for providing high-bandwidth transmission
in the harsh environments found in tunnel drilling and
mining applications, where industrial Ethernet over fibre
optic cable is becoming the transmission medium of
choice.
As digitisation makes increasing inroads into these
sectors, the demands placed on the communication and
control cabling become particularly stringent. The long
distances involved, together with the high bandwidths
that are required, make the use of fibre optic cable
essential, but since optical interfaces are very sensitive
to contamination, a rugged and more reliable solution
has had to be devised.
HARTING’s solution for high data rates under these
extreme conditions is the Expanded Beam Cable
Assembly. Its high bandwidth allows the high-definition
video signals used in the vision systems that control the
boring machines and associated equipment to be safely
and securely transmitted. The fibre is safely packed in
a connector housing that cannot be affected by dust,
water or other environmental factors.
In addition, the hermaphroditic mating design of the
expanded beam connectors ensures that regular
disconnection and re-connection of the cabling in
these environments is easier than using standard fibre
optic cabling. Even extending the length of the optical
connection is as simple as connecting an additional
cable, with no need to pay attention to the laying
direction or any additional adaptors. As a result, the
customer saves time and money, and eliminates the
need to match different mating faces in the field.
In addition to applications in mining and tunnel boring
machines, HARTING’s Expanded Beam Cable
Assembly can be used to link networks in other heavy-
duty application areas, including outside broadcast
events, concert and music festival stage installations
and container ports.
