Electronic pressure switches
Ceramic sensor with thick film technology for high accuracy
Electronic evaluation of switching point permits extremely small
or very large hysteresis settings
Switching point easily set by the user (menu guided for type 0570)
CE marking
SUCO electronic switches are
covered by the EMC Directive
89/336/EC.
An EC Declaration of
Conformity has been issued
for these pressure switches
and is on file at our offices.
The corresponding switches
bear the CE mark in our
catalogue.

The type approval does not
apply without restriction to all
environmental conditions. It is
the responsibility of the user to
check whether the electrical
connection complies with
regulations other than those
stated and whether it can be
used for special applications
which could not be foreseen by
us.
Oxygen warning!
When using oxygen, the
relevant safety regulations
must be observed. In addition,
we recommend that a
maximum operating pressure
of 10 bar must not be exceeded.
