Collocation
When collocating the
sensors, a minimum separation must
be kept between the devices. When in
doubt, a test should be conducted
under application conditions. for
flush mounting the lateral
separation between two sensors must
correspond to at least the diameter
of the sensor. For non flush
mounting, the lateral separation
from each other must correspond to
at least twice the diameter of the
sensor. For oppositely mounted
sensors, a minimal separation of six
times the rated operating distance
should be allowed.
Torques
In order to prevent
destruction of the threaded bushing
during fitting, the following
maximum torques must not be
exceeded:
Instructions for
operation
Serial Connection
For the
serial connection of two wire or
three wire sensors the individual
voltage drops are added together.
Therefore there is a lesser
operational voltage at the disposal
of the load. The addition of the
switch-on delay times should be
noted.
Parallel connection
The
parallel connection of two wire
sensors can only be conditionally
recommended since the residual
currents are added together and flow
through the load. For the parallel
connection of three wire sensors,
the current consumption of the
individual devices is added together.
Since this current does not flow
through the load, the maximum number
of parallel connectable three wire
sensors depends only on the power
supply.
Approval for safety applications
Sensors for personal
security must have a qualification
approval according to EN 954-1 and
must be labeled accordingly.
Sensors that are not labeled must
not be used for applications of the
kind.
Metal face sensors
The
inductive proximity switches series
T are used in areas with heavy-duty
mechanical loads at the sensor's
face or where seals between face and
housing cannot be used. Chips
hitting the front or frequently
changing coolants or lubricants do
not diminish the function of these
proximity switches. Metal face
switches are manufactured from
stainless steel and are one solid
piece. They detect iron and steel
through the metal front face.
120
C-High
Temperature switches
The
These sensors are designed for
particularly difficult and
aggressive environmental conditions.
They can be used in damp and
aggressive environments as well as
under water (oil).
H-
Series proximity switches are
designed for use in temperatures up
to 120 C.
