Beijing Zhongxi Harmony teaches you if you choose the electric plug lock

**Electric Plug Lock: An Electronic Door Locking System** An **electric plug lock**, also known as an **electrical latch**, is an electronic locking device that controls the locking and unlocking of a door by extending or retracting a "lock tongue" via an electric current. The mechanism relies on a magnet to assist in closing the door, ensuring a secure and stable operation. Typically, an **electric plug lock** consists of two main components: the **lock body** and the **keyhole**. Inside the lock body, the key part is the **"lock tongue"**, which interacts with the keyhole to switch between the **"closed"** and **"open"** states. When the tongue is extended into the keyhole, the door is locked; when it retracts, the door can be opened. This retractable feature is what gives the lock its name and makes it ideal for use in **swinging doors** that open in both directions. Additionally, its **hidden installation design** makes it suitable for areas where security and aesthetics are important. **Key Performance Features of Electric Plug Locks:** 1. **Bolt Force**: A strong bolt is essential to ensure reliable locking. If the force is too weak, the bolt may retract automatically or fail to return properly, compromising the lock’s function. 2. **Operating Temperature**: While all electric plug locks generate some heat during operation, excessive heat (like "boiling eggs") is a sign of poor design or overheating. 3. **Working Current**: This depends on the strength of the bolt and the lock's internal temperature. A well-designed system should balance these factors to maintain efficiency and longevity. 4. **Working Voltage**: Common voltages are 12VDC and 24VDC, with 12VDC being more widely used. However, 24VDC offers the advantage of lower operating current, making it more energy-efficient. 5. **Lock Body Size**: For specific installations, the size of the lock body is crucial. Some projects may require custom dimensions that standard models cannot accommodate. 6. **Feedback Signal**: High-end models offer status detection features, such as monitoring the position of the magnetic disk or the lock cylinder. These functions enhance security and provide real-time updates to control systems. 7. **Delay Design**: Some electric plug locks include a delay feature that allows the door to close automatically after a short period. This is useful for access control systems that lack built-in delay capabilities. **How to Choose a Reliable Electric Plug Lock:** When purchasing an electric plug lock, check for a **metallic finish** without scratches. The **standby current** should be around 300mA, and the **operating current** should be below 900mA. After long-term use, the surface should feel slightly warm but not hot. The lock must have enough force to pop back up when pressed. It’s best to test it with at least **4,000 on-off cycles**. If it fails to retract or lacks power, it’s likely substandard. **Two-Wire vs. Multi-Wire Electric Locks:** A **two-wire electric plug lock** is simpler, using a solenoid coil driven directly by current. However, it tends to consume more power and generate more heat, potentially damaging the unit over time. In contrast, **multi-wire locks** are controlled by a microcontroller (MCU), offering better performance, lower heat, and additional features like **delay control** and **door magnetic detection**. These advanced features improve reliability and compatibility with modern access control systems. Although they may cost more, investing in a multi-wire model ensures better quality and long-term stability. Don’t compromise on safety just to save a few dollars.
