Usually the electrical latch consists of two main parts: the lock body and the keyhole. The key component in the lock body is the "lock tongue", and the "keyhole" cooperation can realize the "closed door" and "open door" two states. That is, the lock tongue is inserted into the lock hole to close the door, and the lock tongue leaves the lock hole to open the door. It is because of the retractable function of the tongue that the name of the “electric plug†is awarded. It is also because of this feature that electrical plug locks are often used for various swing doors (two-way opening). At the same time, the characteristics of its “hidden†installation are more suitable for places where the confidentiality of the lock body is relatively high.
Electric plug lock performance:
1. The force of the bolt: if the bolt is weak, the phenomenon of automatic retraction of the bolt may occur, or the reaction force is poor, and the bolt may not be retracted in time, losing its significance of “lockingâ€.
2. The lock body temperature under working condition: There is no electric plug lock that does not generate heat under working conditions, but it should not reach the level of “boiled eggsâ€.
3, working current: This indicator is related to the power of the bolt, but also related to the temperature of the lock body working state. A properly designed electrical plug lock should find a balance between the two.
4, the working voltage: There are usually 12VDC/24VDC two, and mostly 12VDC. The greatest benefit of 24VDC is that it requires less operating current.
5, lock body size: For places with special installation dimensions, this indicator is particularly important. Some project size requirements cannot be achieved by the design.
6. Feedback signal: Some electric plug locks provide the detection function for the lock status, such as the detection of the position of the magnetic disk, the detection of the status of the lock cylinder, and the like. Higher security requirements can be achieved.
7, delay design: can be achieved after a few seconds delay after the door automatically closes the door. This feature is designed for some access control systems that cannot set up delays.
How to buy an electric lock?
First of all, the lock surface must have metallic luster, can't have obvious scratch, the standby current is about 300mA, the operating current is lower than 900mA. After a long period of electricity, the surface is slightly hot but not hot. The electric plug lock must have enough force to bounce off. When pressed down, the lock can automatically bounce up and forcefully. It is best to perform 4,000 on-off tests. If, in the process of discovery, the lock is weak, or it does not pop up, or it may If you do not, it is considered unqualified.
Is the purchase of two-wire or multi-wire electrical plug it? Yes, multi-line electrical plug is controlled with a single-chip, the operating current of the electrical lock is controlled by the MCU intelligent, the lock body will not be too hot, but also with Delay control function and door magnetic detection function; Delay control function can adapt to the poor use of the door spring, door magnetic monitoring function for the controller to provide real-time monitoring of door open and closed state. Although these functions may not be available to you, the quality of the electric locks and the stability of the electric locks controlled by the SCM and the SCM are not on one level. Therefore, it is recommended that you do not need to save a little money. The two-wire power plug lock has a very simple internal structure and is just a current-driven solenoid coil mechanism. The operating current is large and the heat will be severe enough to damage the electrical lock.
