The sound and magnetic anti-theft device uses the principle of the tuning fork to generate resonance through the vibration of the sound and emit an alarm sound. The radio-frequency anti-theft device uses a low-frequency electronic signal to send out an alarm by transmitting and receiving electronic signals. But in the actual use of these two technologies, we discovered that acoustic and magnetic alarms performed much better, not only in terms of theft distance, anti-interference, or false alarm rate, but also stronger than radio-frequency anti-theft devices. The product cost of the anti-theft device is also much higher, which is also the direct reason why the sound and magnetic anti-theft device is expensive.
High-end clothing stores should use sound and magnetic anti-theft devices, mainly due to the value of goods, high-end clothing stores are generally more expensive clothing, stolen situations will be a big loss. The use of radio frequency systems, in the anti-theft performance is worse, can not fully protect the safety of clothing, in the detection of distance, false positive rate should be higher, which is easy to bring unsafe clothing products.
After years of experience in the industry, our company's security door products have gained a good reputation. The supermarket clothing store's anti-theft brand has also emerged as the best in the industry. The products are widely used in supermarkets, shopping malls, clothing chain stores, cosmetics stores, The library, school library and other places have received a consistent good reputation and have become high-quality anti-theft brands.
1, RFID system (full name: radio frequency identification system; low frequency 125K, high frequency 13.46M UHF: 900MH)
2, AM system (full name: acoustic and magnetic goods anti-theft system frequency: 58KHz)
3, RF system (full name: radio frequency system frequency: 8.2MHz and individual others)
4, EM system (full name: electromagnetic anti-theft system frequency: 1-2MHz)
Different systems have different functions and use environments, usually EM systems are used for library books, AM and RF systems are suitable for supermarkets, clothing stores, etc.
Pan Head Drilling Screws With Tapping Screw
Pan head self-tapping screw with self-drilling tip, usually fixing metal elements to each other, or plastic, wood and other materials on metal. Pan Head Drilling Screws With Tapping Screw can be used for thicker materials than sheet metal screws, such as thin-walled rolled and drawn profiles. The thread is identical to the screws in the sheet.
Pan head drilling screws with tapping screw are a type of fastener that have a flat, circular head with a slightly rounded top and a flat underside. These screws are designed to be used with a drill or power tool for easy installation.
The pan head refers to the shape of the screw head, which resembles a shallow pan. This design allows for a larger surface area to distribute the force applied during installation, reducing the risk of the screw head sinking into the material being fastened.
The drilling feature of these screws means that they have a self-drilling tip, often referred to as a drill point or self-tapping point. This point is designed to cut through the material being fastened, eliminating the need for pre-drilling a hole. This feature makes installation quicker and more efficient, as it combines the drilling and fastening steps into one.
Pan head drilling screws with tapping screw are commonly used in applications where a secure and durable fastening is required. They are often used in construction, woodworking, metalworking, and other industries. These screws can be used with a variety of materials, including wood, metal, and plastic.
In summary, pan head drilling screws with tapping screw are versatile fasteners that have a flat, circular head and a self-drilling point. They are designed for easy installation with a drill or power tool and are commonly used in various industries for secure and efficient fastening.
