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:
The set is available in white or brown.
door/window contact set 290, white: 5WG1
290-7AB11
door/window contact set 290, brown: 5WG1
290-7AB81
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.
