Fast and accurate data transmission
Leuze electronic has developed a data
transmission photoelectric sensor that has
a high optical transmission of 100 Mbit/s.
Available from sole Southern African dis-
tributors Countapulse Controls , the device
allows data transmission without cabling and
without interference. Gerry Bryant, managing
director of Countapulse Controls, says that
the Leuze DDLS 500 optical data transceiver
is able to instantaneously transmit all com-
mon Ethernet protocols up to distances of
120 metres.These protocols include Profinet,
EtherNet IP, EtherCat, Ethernet TCP/IP and
Ethernet UDP. Constant monitoring and noti-
fication of the signal level on the easy to read
LED display allows quick reaction to issues
like soiling of the lens, ensuring simplified
maintenance and diagnostics. The modular
design of the Leuze DDLS 500 includes an
integrated bubble level for accurate installa-
tion.The patented single-hand adjustment of
the instrument allows precise alignment of
the data light beam. In addition, the device
projects four laser spots on the floor along
the intended light path, aiding in the easy
alignment of the device at a distance.

Motion detectors provide automated light switching
RET Automation Controls has introduced the WLS28-2MQ motion detector switch for
automated lighting. Banner’s motion detector switches provide an efficient solution to
automatically turn on or off the light in applications where a physical switch cannot be
used or the placement of the switch is not useful.
Banner’s motion detector switches are available in two options, an in-line module or
built-in motion detector for the company’s industry-recognisedWLS28-2 LED Strip Light.
The in-line module allows operators to place the motion detection switch away from
the light, and can be used with any Banner dc voltage lights.TheWLS28-2 with built-in
motion detector models provide easy and fast installation in one place.
“The motion detection switch offers a simple, convenient lighting solution for applica-
tions that don’t easily allowmanual on/off switching,” saidMatt Hahn, technical marketing
engineer for lighting at Banner Engineering. “For example, if the motion detection switch
is inside of an electrical enclosure, it will automatically turn the light on when the door
is open and off when it is closed.”
The motion detector switches feature M12 connectors and rugged metal housing
for secure, durable performance. Detector switches are rated for 12 to 30 Vdc. Banner’s
WLS28-2 LED Strip Light delivers a versatile lighting solution, featuring a space-saving,
low-profile design and various lengths from 145 mm to 1 130 mm.

New software for inventory
visualisation
Imagine communicating automatically with the
supplier of your level and pressure instrumenta-
tion via aWeb portal. Imagine a situation where
the sensors you have installed on tanks or silos
at your plant not only communicate with each
other and your plant management system but
also with your supplier.
Vendor-managed inventory (VMEI) pro-
grammes are not a new idea. Major companies
across leading industries have adopted this
business model as a way to optimise inventory
management and supply chain efficiencies.
The automated flow of information within a
company or between partner companies cre-
ates transparency early on for the supplier and
security of supply for the purchaser.
VEGA, one of the market leaders in the manu-
facture and supply of pressure and level sen-
sors, has made a strong link out of something
that until now was a critical weakness in the
supply chain.TheVEGA Inventory Systemallows
sensors to communicate directly withVEGA fully
automatically, and report the need for re-supply.
With the help of the web-based software, VEGA
assumes responsibility for the customer’s stocks
and makes sure they are always sufficiently
supplied.The customer no longer has to assess
his needs accurately and thenmake sure replen-
ishments are ordered on time. VEGA Inventory
System takes over this accomplish
this task, the software provides automatic alerts
to VEGA, which in turn allows VEGA greater
flexibility in their own resource and logistics
management. The programme also includes a
series of well-designed analytical and planning
tools that enables optimised demand, inventory
and delivery planning.
