Stainless steel encoders with IO-Link
Turck is completing its range of contactless
EQR24 stainless steel encoders with an
IO-Link variant. A variant with an IO-Link
interface completes from JuneTurck's port-
folio of wear-free stainless steel encoders.
The robust stainless steel variants of the
contactless QR24 inductive encoder series
are specially designed for operation in
applications with particular requirements
for cleaning or for extreme environmental
conditions, such as in the food and beverage
or heavy industry.The EQR24 series consists
of models with SSI, incremental, analog
and IO-Link outputs. With a V4A stainless
steel housing (1.4404) and an active face
made fromPA12-GF30 plastic the device can
withstand even the harshest chemicals and
pressures in the cleaning process.
As with all QR24 models, the sensor and
positioning element are fully potted and cast
as two totally sealed independent units that
can withstand any vibration or shocks of the
shaft. Wear-intensive ball bearings or seals
which lead to machine downtimes and thus
long maintenance times are not required.
Thanks to its intelligent mounting concept
using adapter rings, the permanently sealed
IP69K encoder can be fitted on all standard
shafts with diameters up to 20 mm.

Latest solutions, IOT devices at African Automation Fair 2017
Omron’s EtherCat solutions and Inter-
net of Things (IOT) devices will take
centre stage at the African Automa-
tion Fair (AAF) from 6 - 8 June 2017
atTicketpro Dome in North Riding, Jo-
hannesburg. In particular, a new IOT
EtherCat module will be launched.
There will also be a strong em-
phasis on Omron’s Sysmac motion
solutions, comprising robotics and
visual inspection control,Victor Marques, Country General Manager,
highlights. “Historically, AAF has always had a good reach into all
of our relevant industries. Of course, we also have the correct target
market attending our stand.”
The scope of AAF 2017 has evolved with the inclusion of IOT
as one of the latest and most pervasive trends in the automation
industry. This is an exciting outcome of the digital revolution that
is changing the way we live and work.
Marques highlights that Omron’s presence will appeal directly to
customers on the lookout for cost-effective and highly-innovative
solutions that meet, and even exceed, their requirements. “We are
looking to target OEMs in particular, and food and beverage end-
user customers,” Marques points out. The Omron product range
on display at AAF 2017 includes Sysmac motion and PLC control,
NX remote I/O, vision systems, safety products, servos, Variable
Speed Drives (VSDs), Human Machine Interface (HMI), and general
control components.
“We have strong experience and references in areas such as mo-
tion and drive control, PLCs and HMI, automation networks, and
visual inspection control and robotics,” Marques reiterates. Omron
Field Sales Engineers will man the stand at AAF 2017 to familiarise
customers with the latest technology.
“We will also have Application Engi-
neers on hand with a wealth of experi-
ence to field high-end technical ques-
tions. Different managers will also be
present on different days to showcase
our commitment in meeting our custom-
ers’ needs from the top down,” Marques
concludes. Visit Omron at Stand E25,
E28, AAF 2017.

Miniature encoder for mobile equipment
The contactless resonator measuring
principle enables the compact Ri360-QR20
to be wear-free and permanently sealed.
Turck's compact and wear-free Ri360-QR20
miniature encoder is especially designed for
use in mobile machinery.The new encoder
series with IP68/IP69K protection exceeds
the e1/E1 requirements and comes in a
compact 71 x 64 x 20 mm housing. It is
based on the contactless resonator measur-
ing principle like its “big brother”, the QR24.
The key feature:The housing fully surrounds
the positioning element and provides it
with full protection from the outside. Al-
ternatively, the positioning element can
also be positioned above the sensor. This
design principle not only reduces the plan-
ning work for the designer, but also offers
mechanical protection, as well as protec-
tion from dust and moisture. The housing
is also permanently sealed. Even the often
problematic potential points of leakage such
as LED lenses are eliminated since the QR20
uses a translucent plastic.
Available from RETAutomation Controls,
the encoder offers interference immunity of
100V/m and is protected from line-conduct-
ed interference according to DIN ISO 7637-2
or SAE J113-11, the so-called load dump.
Salt spray or rapid temperature changes, as
well as diesel, kerosene or vibrations have
no effect on the device.With a temperature
range from -40 to +85°C there are virtually
no climatic conditions that could be critical
for the QR20.The Ri360-QR20 offers a 12-bit
resolution on the output side, correspond-
ing to around 0,09 degrees. The output
signal ranges from 0,5 to 4,5 Vdc (LU4). If
the sensor does not detect a positioning
element, the value jumps to 5 V.
