Electromagnetic Locks Features
Electromagnetic locks are designed to take advantage of the physics behind electromagnetism. An electromagnetic lock comprises two main parts, an armature plate made of metal and steel plate surrounded by a coil of wire which can be magnetized. When an electrical current passes though the coil, the steel plate becomes magnetized and strongly attracts the armature plate, locking the door.
Electromagnetic locks deliver high performance. For example, our HS-EML-750D series of electromagnetic locks, with a maximum holding force of 750 kg (1500 lbs), only use 1.8W of power to produce up to 240 kg (530 lbs) of holding force.
The holding force capability of each of our electromagnetic locks is tested in a collinear load test. The electromagnetic lock is loaded in a rig with power being supplied so that the electromagnet strongly attracts the armature plate. Then force is slowly applied to pull the armature plate away from the electromagnet. When the mechanical pulling force overcomes the magnetic force, the force is the strength of the electromagnet.
This figure shows the relationship between voltage and holding force. Voltage is proportional to power consumption when the current is fixed. Holding force is proportional to voltage until holding force reaches a maximum. At this point, any further power consumption will not increase holding force.
Electromagnetic locks are protected by epoxy potting compound which ensures a long life for the lock. The lock itself is strong and robust. All the advantages of electromagnetic locks have made them very popular, becoming one of the most widely installed types of electric locks by security engineers.
Electromagnetic locks use magnetic force and thus do not require a mechanical latchbolt to lock the door. This makes them very suitable for emergency and fire exits. In case of emergency, electromagnetic locks automatically release the doors upon power cutoff. There is no concern over the door unable to be opened due to mechanical failure.
