Product Description

The CA30CA.. capacitive
proximity switches feature
an improved 4TH Genera­tion TRIPLESHIELDTM tech­nology. Furthermore, these
sensors feature increased
immunity to electromagnetic
inteference (EMI), especial­ly to frequency drives. Not
only does 4TH Generation

TRIPLESHIELDTM feature

an increased EMI, but it
also increases the immuni­ty to humidity and dust. The
implementation of stability
indication eases the setup
procedure as both Stable ON
and Stable OFF positions are

indicated by the Green and
yellow LEDs.
The sensing distance is
increased by 20 – 25 %
allowing room for additional
stable detection.
The Dust Alarm function
gives an early warning that
the sensing surroundings
have to be cleaned.
The Temperature alarm func­tion raises an alarm if the
sensing surface goes beyond
60 degree celcius.
The sensor housing is featur­ing IP69K as well as approval
by ECOLAB for cleaning­and disinfection agents.

* The IP69K test according to DIN 40050-9 for high-pressure, high-temperature wash-down applications.
The sensor must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning.
The sensor is exposed to high pressure water from a spray nozzle that is fed with 80°C water at 8’000–
10’000 KPa (80–100bar) and a flow rate of 14–6L/min. The nozzle is held 100 –150 mm from the sensor at
angles of 0°, 30°, 60° and 90° for 30s each. The test device sits on a turntable that rotates with a speed of 5
times per minute. The sensor must not suffer any damaging effects from the high pressure water in appear
ance and function.

Installation Hints

Capacitive sensors have a
unique ability to detect al­most any material in li quid or
solid form. Capa ci tive sen­sors are able to detect me­tallic as well as non-metallic
ob jects. How ever, their tradi­tional use is for non-metallic
materials such as:

• Plastics Industry
Resins, regrinds or mould-

ed products.

current peaks, separate the prox. switch pow­er cables from any other power cables, e.g.
motor, contactor or solenoid cables

Delivery Contents

• 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.

Relief of cable strain

Not correct

Correct

The cable should not be pulled

Protection of the sensing face Switch mounted on mobile carrierTo avoid interference from inductive voltage/

A proximity switch should not serve as
mechanical stop

• 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 ma­terial, the better or easier it is
to detect the object.

Any repetitive flexing of the
cable should be avoided

Accessories

The nominal sensing di stan­ce for a capacitive sensor
is refe r red to a grounded
me tal plate (ST37). For addi­tional information regarding
