When evaluating an electric strike lock, the first thing to check is the surface finish. It should have a metallic sheen and be free from noticeable scratches. The standby current should be around 300 mA, while the operating current must remain below 900 mA. After prolonged use, the surface may feel slightly warm, but it shouldn’t become excessively hot. The locking force needs to be strong enough—when pressure is applied, the lock should snap back quickly and with power. Ideally, it should pass 4,000 on-off cycles. If during testing the lock feels weak, doesn’t return properly, or fails to lift, it’s considered substandard. Some engineers often ask whether the electric strike lock uses a two-wire or multi-wire system. Multi-wire electric locks are typically controlled by a microcontroller, which regulates the operating current and prevents overheating. They also offer delay control and magnetic door detection features. The delay function helps doors with weak springs, while the magnetic door monitoring ensures real-time status updates. Although these functions might not always be necessary, the quality and stability of microcontroller-based locks are generally superior to those without. So, it's better not to cut corners for small savings. Two-wire electric locks, on the other hand, have a simpler internal design that relies on a direct electromagnetic coil activation. This leads to higher current draw and more heat generation, which can damage the lock over time. Therefore, they’re not recommended for long-term use. When purchasing an electromagnetic lock, look for a sleek and well-finished exterior with no visible scratches or rust. The key factor is the tensile strength, which requires professional equipment to measure. After installation, you can test it by pulling suddenly. A slight pull is normal, but the lock body should be installed correctly. Avoid tightening the magnet too much, as this could affect its performance. Before buying a smart lock, consider whether to go for a domestic or imported model. While imported electric locks are known for their maturity and low failure rates, they come at a high cost—usually over 1,000 units. Additionally, service can be an issue if problems arise, as foreign support might be slow or unresponsive. I recommend choosing a domestic option instead. These locks are affordable, often manufactured in Taiwan (a major OEM supplier for foreign brands), and meet similar quality standards with minimal differences. When deciding between an electric lock, electromagnetic lock, or electric plug lock, it depends on your specific application. For double-acting glass doors, an electric plug lock is ideal. For single-acting wooden doors, an electromagnetic lock (also called a magnetic lock) is more suitable. Magnetic locks are installed on the top of the door frame, and while some find them unsightly, they are commonly used abroad. They offer greater stability than electric plug locks, though electric locks provide higher security. Electric locks are installed on the door edge along with mechanical locks like ball locks, but they tend to be less secure and harder to wire. They are cheaper, but not recommended for most applications. For residential buildings, magnetic locks and electric locks are preferable. Some electric locks can be quite loud, so silent models are now available and worth considering. No matter the type, ensure the lock is protected from rain, as iron components are prone to rust. There are many less popular electric lock types on the market, such as power-off locks. These keep the door closed during power outages but may not meet fire safety regulations and require thick door frames, leading to potential issues. It’s safer to stick with proven options. Always choose reliable and widely used products for better performance and fewer headaches.
