Wide light band
for reliable detection
F
eaturing a wide light band, the Leuze
RK 46C.DXL VarOS retro reflective
sensor is able to reliably detect both
small and large objects. Objects can be
round, angular or both, with glossy sur-
faces, have transparent shrink wrapped
film or even be totally black, with gaps or
with high ambient light levels. These Leuze
sensors are ideal for when the objects to be
detected or the associated environmental
conditions deviate from the norm.
The Leuze RK 46C.DXL VarOS retro
reflective sensor is particularly effective in
this regard as it responds to objects with the
entire width of its light band, which gives it
the capability to handle interruptions. The
wide light band allows for detection over a
45 mm to 60 mm wide area.
The sensitivity and/or resolution of the
sensor can be adjusted easily by means of
a button located on the rear housing. This
Leuze sensor also features a handy ‘teach
me’ function, which allows it to be adapted
easily between two object sizes greater
than 8.0 mm at the touch of a button. This
ensures optimum flexibility of application.
The use of this sensor does away with the
need for expensive light barriers or multiple
individual sensors.
Other features include the ability to
calibrate for detection of transparent,
perforated or small objects as well as to
reliably detect objects with depolarising
media such as foil packaging.
Germany-based Leuze Electronic has
been solving sensing problems for more
than 50 years for use in industrial automa-
tion systems. With subsidiaries all over the
world and over 1 000 employees, custom-
ers can rely on the competent consultation
and reliable customer service offered as
well as solid application know-how and
comprehensive industry knowledge.
The Leuze RK 46C.DXL VarOS retro
reflective sensor is available in South Africa
from Johannesburg-based Countapulse
Controls, the leading southern African
supplier of sensing, measurement, count-
ing, switching, monitoring and positioning
instrumentation. With over 40 years expe-
rience in sensing technology, Contapulse
controls offers reliable, efficient and ap-
plication appropriate sensing, control and
motion detection solutions.
As well as offering the Leuze range of
photoelectric sensors, other brands lo-
cally represented by the company include
Hengstler counters and encoders, EGE
flow monitoring and specialised sen-
sors, Pulsotronic inductive sensors, ABP
drive components and Secatec magnetic
switches.
Contapulse controls also offers a com-
plete technical advisory service for the most
effective use of its products in automotive
and other branches of engineering.
