The MC 340 series are universal magnetic contacts used in both alarm and security access control systems for the protection of doors, gates and windows against unauthorised opening. A wide range of installation accessories allows the contacts to be surface- or recessed-mounted. The magnetic reed and magnet assemblies are enclosed in a waterproof (IP 67) plastic ABS housing, with 3 catch-bolts each. This enables stopping them into either a wooden frame or inside an accessory for installation on an element made of steel or other material.
