The environments in which capacitive sensors are installed can
often be un
stable regarding tem-
perature, humidity,
object distance
and industrial (noise) interference.
Because of this, Carlo Gavazzi
offers as standard features in all
TRIPLESHIELD™ capacitive sensors a user-friendly sensitivity
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 maximum rated sensing range.
Adjustment Guide
Installation Hints
Capacitive sensors have the
unique ability to detect almost all
materials, either in liquid or solid
form. Capacitive sensors can
detect metallic as well as nonmetallic 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 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 material, the
better or easier it is to detect the
object. Nominal sensing distance
for a capacitive sensor is referenced to a grounded metal plate
(ST37). For additional information
regarding 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 carrierTo avoid interference from inductive voltage/
current peaks, separate the prox. switch power 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
