Product Description

The CA18CA.. capacitive

proximity switches feature

an improved 4

Genera-

tion TRIPLESHIELD

tech-

nology. Furthermore, these

sensors feature increased

immunity to electromagnetic

inteference (EMI), especial-

ly to frequency drives. Not

only does 4

Generation

TRIPLESHIELD

feature

an increased EMI, but it

also increases the immuni-

ty 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 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 func-

tion raises an alarm if the

sensing surface goes beyond

60 degree celcius.

The sensor housing is featur-

ing IP69K as well as approval

by ECOLAB for cleaning-

and disinfection agents.

CA18CAN/CAF..... Adjustment Guide The environments in which capacitive sensors are installed can often be unstable as regards to temperature, humidity, object distance and industrial (noise) inter ference. Because of this, Carlo Ga vazzi offers as standard features in all TRIPLESHIELDTM capacitive sensors a user-friendly sensitivity adjustment instead of a fixed sensing range.

CA18CAN/CAF..... Installation Hints Capacitive sensors have a unique ability to detect al most any material in liquid or solid form. Capa ci tive sensors are able to detect me tallic as well as non-metallic objects. However, their traditional use is for non-metallic materials such as: • Plastics Industry Resins, regrinds or mould ed products. To avoid interference from inductive voltage/ current peaks, separate the prox. switch power cables from any other power cables, e.g.
