Adjustment
(4-wire device backview)
The environments in which
capacitive sensors are install-
ed can often be unstable re-
garding temperature, humidity,
object distance and industrial
(noise) interference. Because
of this, Carlo Gavazzi offers as
standard features in all TRIP-
LESHIELDTM capacitive sen-
sors a user-friendly sensitivity
adjustment instead of having
a fixed sensing range, extend-
ed sensing range to accom-
modate mechanically demand-
ing areas, temperature stability
to ensure minimum need for
adjusting sensitivity if temper-
ature varies and high immunity
to electromagnetic interfer-
ence (EMI).
Note:
Sensors are factory set (de-
fault) to maximum rated sens-
ing range.
Adjustment Guide
Installation Hints
Capacitive sensors have the
unique ability to detect almost
all materials, either in liquid or
solid form. Capacitive sen-
sors can detect metallic as
well as non-metallic objects,
however, their traditional use
is for non-metallic materials
such as:
Plastic Industry
Resins, regrinds or moulded
products.
Chemical Industry
Cleansers, fertilisers, liquid
soaps, corrosives and
petrochemicals.
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 vegeta-
bles, dairy products.
Materials are detected due to
their dielectric constant. The
bigger the size of an object, the
higher the density of material,
the better or easier it is to de-
tect the object. Nominal sens-
ing distance for a capacitive
sensor is referenced to a
grounded metal plate (ST37).
For additional information re-
garding dielectric ratings of
materials please refer to
Technical Information.

Installation Hints (cont.)
Relief of cable strain
Protection of the sensing face
Switch mounted on mobile carrier
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
Incorrect
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
