Installation Hints
Capacitive sensors have a
unique ability to detect al-
most any material in li quid or
solid form. Capa ci tive sen-
sors are able to detect me-
tallic as well as non-metallic
ob jects. How ever, their tradi-
tional use is for non-metallic
materials such as:
• Plastics Industry
Resins, regrinds or mould-
ed products.
• Chemical Industry
Cleansers, fertilizers, liq-
uid soaps, corrosives and
pe t ro chemicals.
• Wood Industry
Saw dust, paper products,
door and window frames.
• Ceramics & Glass
Industry
Raw materials, clay or
finish ed products, bottles.
• Packaging Industry
Package inspection for lev-
el 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.
The nominal sensing di stan-
ce for a capacitive sensor
is refe r red to a grounded
me tal plate (ST37). For addi-
tional information regarding
di elec tric ratings of materi-
als please re fer to Technical
Information.
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
