CD46, DC, Teach-in
The environments in which
capacitive sensors are install -
ed can often be un
stable re -
garding temperature, humi dity ,
object distance and industrial
(noise) interference. Because
of this, Carlo Ga
vazzi offers
as standard features in all
TRIP LESHIELDTM capacitive
sensors a user-friendly sensi-
tivity adjustment instead of
having a fixed sensing range,
extend ed sen
sing range to
accommodate mechanically
demand ing are as, temperature
stability to en
sure minimum
need for adjusting sensitivity if
temperature varies and high
immunity to elec
tro magnetic
interference (EMI).
Adjustment
Installation Hints
Capacitive sensors have the
unique ability to detect al
-
most all materials, either in li -
quid or solid form. Capa ci tive
sensors can detect metallic
as well as non-metallic ob
-
jects, how ever, their tradition-
al use is for non-metallic
materials such as:
Plastics Industry
Resins, regrinds or mould -
ed products.
Chemical Industry
Cleansers, fertilisers, liquid
soaps, corrosives and pe -
t ro chemicals.
Wood Industry
Saw dust, paper products,
door and window frames.
Ceramic & Glass
Industry
Raw material, clay or
finish ed products, bottles.
Packaging Industry
Package inspection for level
or contents, dry goods,
fruits and vegetables, dairy
products.
Materials are detected due to
their dielectric constant. The
bigger the size of an object,
the higher the density of ma -
terial, the better or easier it is
to detect the object. Nominal
sensing di stan ce for a capaci-
tive sensor is refe r enced to a
grounded me tal plate (ST37).

tional information

To avoid interference from inductive voltage/
current peaks, separate the prox. switch pow-
er cables from any other power cables, e.g.
motor, contactor or solenoid cables
Not correct
Correct
The cable should not be pulled
A proximity switch should not serve as
mechanical stop
Any repetitive flexing of the
cable should be avoided

Wiring Diagrams
By means of the Teach-in wire, the functions described
in the Teach-in Guide can be setup.
It is possible to Teach-in more sensors at the same time
by connecting the WH-wires in parallel to the common "-
" supply.
(#): Plug connections
Important NPN: If alarm output (WH-wire) is unused, it
has to be terminated to +supply
Important PNP: If alarm output (WH-wire) is unused, it
has to be terminated to supply
