MC 746 is a small and thin magnetic contact with change-over (NC/NO) function that can be used in both alarm and access control systems for monitoring e.g. doors and windows against unauthorized opening. Both the contact and the magnet part are in a water proof (IP 67) plastic housing. The small and thin format makes it especially easy to install in limited spaces, e.g. on shutters and drawers. With lid for the screw holes.
