Adjustment Guide
having
fixed
a
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
TRIPLESHIELD™ capacitive
sensors a user-friendly sensi-
tivity adjustment instead of
sensing range, extended sen-
sing range to accommodate
mechanically demanding are-
as, temperature stability to
ensure minimum need for
adjusting sensitivity if temper-
ature varies and high immun-
ity to electromagnetic interfer-
ence (EMI).

Installation Hints
Delivery Contents
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 traditi-
onal use is for non-metallic
materials such as:
• Wood Industry
Saw dust, paper products,
door and window frames.
• Capacitive switch: CB32CL...
• Screw driver
• Packaging: Plastic bag
• Installation & Adjustment Guide
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).
For additional information
regarding dielectric ratings
of materials please refer to
Technical Information.
• Plastic Industry
Resins, regrinds or moulded
products.
• Agriculture
Feed, solids or grain.
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
Any repetitive flexing of the
cable should be avoided
A proximity switch should not serve as
mechanical stop
