Switch IO 102-K (VK-1)

IO 102-K (VK-1) security magnetically contact detector is designed for locking doorways and windows, arranging "trapping" medium as well as locking other elements of buildings with an alarm signal raised to a control panel, concentrator or central surveillance system by opening reed switch contacts.

Detector consists of a button connected with the driving magnet and reed switch in plastic housing. It is designed for continuous operation.

Is realized on any surfaces in the preperforated opening Ø12,5mm by two screws M3 with flat head. Thickness of the surface should be no more than 3 mm. Switching on can be performed by force, applied either perpendicularly or parallel to mounting face. At parallel force of switching on gap 0.3 mm must be kept and in is necessary to have eased edge of switching surface of radius no less than 0,5mm.
