Product- and Applications Description
The proximity switch is provided as an opening alarm for monitoring
windows and doors. It is operated in a contactless manner
by a separate permanent magnet. If the clearance between
the proximity switch and the magnet increases, the reed contact
opens.
It records the status (open or closed). This information is transferred
to a KNX system via binary reporting inputs. The analysis
of these states is used, for example, for an energy-optimised
heating and climate control system, as well as for safety functions
to monitor the building shell in risk reporting systems.
The proximity switch is provided in a set, consisting of:
-
1 magnet, Ø 8 × 30 mm
-
1 magnetic contact, Ø 8 × 30 mm in an encapsulated plastic
housing, with a 5 m lead cable LiYY 4 × 0.14 mm²
-
2 × housing tops (43 × 12 × 12) mm
-
2 × housing bottoms
-
4 × distance plates 2 × 4 mm or 2 × 2 mm thickness
-
2 x building-in flanges
-
4 × anti-magnetic recess plate screws

The proximity switch is cast into a housing and in this way is
protected against dust and moisture.
It is inset into (built-in) or mounted on (built-on) window and
door frames made from non-magnetic materials. Accordingly,
the magnet contact and magnet are mounted in parallel or facing
each other in the window frame / door leaf or window sill /
door frame.
Mounting on ferromagnetic materials is only permitted with the
use of the housing incl. distance plates.
The housing should only be fixed with anti-magnetic screws.
