Installation Instructions Magnetic contact VdS-C MK1310B/W General description The magnetic contact is designed as a contact combination. It is used as an opening contact sensor for monitoring doors, cases, windows, etc., in plant and equipment that needs to be safeguarded. The housing variants of the magnetic switch including the magnet as built-in and surface-mounted version permit optimal adaptation to the object to be secured. It is suitable for both built-in and surface-mounted installation. The surface-mounted housings are designed to allow the contact to be fitted in either direction. To ensure magnetic insulation in ferromagnetic objects and/or to compensate for any mounting height differences, distance pieces are supplied with the surface-mounted version. This enables it to be installed in a door or window frame or under an object in such a way that an alarm is triggered if the door or window is opened or the object raised by more than 2 cm. Advantages of magnetic contact: - Connections: Inconspicuous, small size High resistance to environmental influences thanks to cast-iron manufacture (IP68) Large switching intervals Extremely high resistance to wear Simple installation Installation (built-in version) Type Drillings for moving and fixed parts Diameter Depth Magnetic contact (8.0 + 0.2) mm 30 mm Magnet (8.0 + 0.2) mm 20 mm In the centre, drill a 4 mm hole for the magnet contact cable. If the cable is surface-mounted, a cable clamp must be provided ca. 15 mm from the housing. Fix the magnet or magnet holder on the moving part of the object to be monitored. Magnetic contacts, magnets or magnet holders can be fixed using an adhesive such as a singlecomponent silicon rubber glue. Important: Make sure that the magnetic contact and the magnet meet! Never use a hammer to fix the magnet in small spaces. Installation (surface-mounted version) The surface components are used for installing the equipment on surfaces of door and window frames. Note: Place the magnet in the holder so that its plastic part is on the same side as the cable to the switch. If contacts are installed on metal doors, the distance must be at least 8 mm so that the strength of the magnet does not decrease in the long term, thereby causing false alarms. The holder has 2 side notches for fitting the cable. When the reed contact has been inserted, the cable can be led through the more suitable notch. This allows the cable to be fitted direct from behind. The cut-out on the holder is used for snapping in the cover. Covers have a thinner section on the side and the end that can be broken out for fitting the cable. This enables the cable to be fitted along the short or the long side. Press the cover onto the holder until it audibly engages. If correctly installed, it can now only be removed by destroying it.
