With their locking based around a large flat surface, electromagnetic locks or ‘mag locks’ as they are also known, can withstand a fair force, as long as they have a constant uninterrupted power supply. One of their main benefits is that they have no moving parts, relying entirely on the electromagnetic connection.
There are two distinct types as detailed below
Fail secure devices remain closed when power is lost.
A “fail secure” magnetic lock remains locked when power is lost and is ideal in higher security areas where security must be maintained
Fail safe devices open when power is lost.
A “fail safe” magnetic lock requires power to remain locked and typically is not suitable for high security applications because it is possible to disable the lock by disrupting the power supply.
