contacts have changed their
open/close condition when the
CLS.. magnetic unit is close to the
sensor (see Technical Data for
operating distances).
The coded structure of the
SMS../CLS.. pairs requires, in
order to operate correctly the
sensors, that the magnetic units
are brought closer to the sensors
following a defined alignment with
them.
3.1
Parallelepiped sensors
The CLS.. unit must be brought
closer to the SMS.. sensors so
that the printed arrows are faced
(see Fig. 4).
The alignment is achieved moving
the CLS.. unit towards the SMS..
sensor along the X axis (side
alignment, e.g. sliding door) or Y
axis (frontal alignment e.g. hinged
gate/door or slide) or

perpendicularly to the XY plane (Z
axis, e.g. hinged gate/door).
A correct positioning is achieved
when the SMS.. sensor and the
CLS.. unit lie on the same XY
plane, aligned to the same
position X0. In that position, if the
distance between the sensor and
the magnetic unit is less than the
Operating Distance (D-ON, see
Technical Data), the sensor is
correctly operated.
Different alignments can lead to
wrong operating conditions (e.g.
none or only one internal contact
changes its status).
Starting from SMS.. correctly
operated by the CLS.. unit as
stated before, and Y distance null,
the sensor can be properly
operated also with the magnetic
unit misaligned along the X axis or
Z axis up to a maximum position
