The environments in which
capacitive sensors are install-
ed can often be un stable re-
garding temperature, humidity,
object distance and industrial
(noise) interference. Because
of this, Carlo Gavazzi offers
as standard features in all
TRIPLESHIELD™ capacitive
sensors a user-friendly sensi-
tivity adjustment instead of
having a fixed sensing range,
extended sensing range to
accommodate mechanically
demanding areas, temperature
stability to ensure minimum
need for adjusting sensitivity if
temperature varies and high
immunity to electromagnetic
interference (EMI).
Note:
Sensors are factory set
(default) to nominal sensing
range S

Adjustment Guide
Installation Hints
Capacitive sensors have the
unique ability to detect al-
most all materials, either in li-
quid or solid form. Capacitive
sensors can detect metallic
as well as non-metallic ob-
jects, however, 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-
trochemicals.
• Wood Industry
Saw dust, paper products,
door and window
frames.
• Ceramic & Glass
Industry
Raw material, clay or
finished 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 distance for a capaci-
tive sensor is referenced to a
grounded metal plate (ST37).

regarding dielectric ratings
of materials please refer to

Dimensions
Relief of cable strain
Protection of the sensing face Switch mounted on mobile carrierTo 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
