FIELD: devices to protect different objects against intrusion.
SUBSTANCE: access code input device comprises magnetic key and reading unit. Magnetic key is made as non-magnetic plate provided with constant magnets. The reading unit includes at least two magnetosensitive sensors connected to non-magnetic base so that they may cooperate with magnetic field of magnetic key. Device has executive mechanism controller electrically connected with each magnetosensitive sensor and providing access code by serial code symbols input. Magnetic key may move over free surface of non-magnetic base facing outer door side. Said surface has hairline. Outer side of magnetic key has hairlines and/or identifying marks.
EFFECT: increased lock secrecy and elimination of unauthorized code input.
