The magnetic contacts of the MK-2000 series are used in alarm signalling systems and security access control systems to protect doors, gates and windows against unauthorized opening. The extensive assortment of installation accessories permit the use of these contacts in almost any inside or outside application.
The magnetic contact consists of two parts, i.e. the reed contact and a permanent magnet. The reed contact
and the magnet are mounted at a defined distance on the fixed and the movable parts of the object to be protected. The reed contact remains closed by the force field of the permanent magnet. If the distance between the reed contact and the magnet increases, the magnetic field becomes weaker in the reed contact and causes the reed contact to open and interrupt the electric circuit.
The installer must ensure that the air gap between the fixed and the moveable parts does not permit
sabotage. The MK-2000 series have a self-cutting and self-locking thread, which permits direct sunk installation in wood and plastic objects without any additional accessories. For installation a hole has to be drilled. The reed contact is screwed into the fixed part of the object to be protected, and the magnetic part is screwed into the moveable part of the object. Because of the very flexible connection cable to
the contact installation is easy, even if the cables have to be bent. For use in other materials or in locations where direct use of contacts and magnets is not possible, a plastic adapter set is available, the contact can be screwed to one side and the magnet to the other.
