Sensitivity
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 LESHIELD™ capacitive
sensors a user-friendly sen-
sitivity adjustment instead of
having a fixed sensing range,
extend ed sen sing range to
accommodate mechanically
demand ing are as, temperatu-
re stability to en sure minimum
need for adjusting sensitivity
if temperature varies and high
immunity to elec tro magnetic
interference (EMI).
Note:
Sensors are factory set (de-
fault) to maximum rated sen-
sing range.
Adjustment Guide
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 traditi-
onal use is for non-metallic
materials such as:
• Plastic Industry
Resins, regrinds or moul-
ded 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 finish-
ed products, bottles.
• Packaging Industry Pac-
kage inspection for level or
contents, dry goods, fruits
and vegetables, dairy pro-
ducts.
Materials are detected due
to their dielectric constant.
The bigger the size of an
object, the higher the den-
sity of material, the better
or easier it is to detect the
object. Nominal sensing di-
stan ce for a capacitive sen-
sor is referenced to a groun-
ded me tal plate (ST37).

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 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
