Today, a client I'm working with suddenly asked me a question like this, and I guess many other clients are also interested in it, so I gave a detailed explanation.The TK4100 and EM4100 are both types of RFID chips that are commonly used for access control and identification purposes. Here's a more detailed comparison:Compatibility:The TK4100 chip is designed to be fully compatible with the EM4100, EM4200, and EM4102 chips. This means that systems designed to work with EM4100 chips can also operate with TK4100 chips without any modifications.Read-Only Memory: Both the TK4100 and EM4100 chips have read-only memory, which is used to store a unique serial number that identifies each chip. This serial number cannot be altered, providing a secure and permanent identification feature.Performance: In terms of performance, the TK4100 chip is said to offer the same capabilities as the EM4100 chip. This includes read range, data transmission speed, and reliability. Users can expect similar performance from both chips in practical applications.Usage: The usage of both chips is quite similar. They are often embedded in access cards, key fobs, and other identification devices. They are used in various applications such as access control systems, attendance tracking systems, and library management systems.Price: One of the key differences between the TK4100 and EM4100 chips is the price. The TK4100 chip is noted for its competitive pricing, which makes it an attractive alternative to the more expensive EM4100 chips. This cost advantage has led many system manufacturers to adopt the TK4100 chip for their products.Market Adoption: Due to its cost-effectiveness and compatibility, the TK4100 chip has seen widespread adoption in many systems that were originally designed for EM4200, EM4100, or EM4102 chips.In summary, the TK4100 chip is a cost-effective alternative to the EM4100 chip that offers the same level of performance and compatibility. It is an excellent choice for applications where budget constraints are a consideration, without compromising on the functionality and reliability provided by the EM4100 chip.

For 14 years, we have enjoyed a successful collaboration with a valued customer. Recently, this customer put forward a special request for the customization of magnetic locks using fireproof materials.In response to this demand, our team embarked on an intensive process. We conducted no less than four proofing sessions to ensure the highest quality and safety standards. Through meticulous selection and evaluation, we chose raw materials that could meet the stringent fire rating requirements.The video provided below offers a clear demonstration. It showcases one material that successfully reached the desired fire rating, while also presenting another that unfortunately did not meet this critical grade.This entire project reflects our commitment to meeting customer needs with precision and excellence.

One of our customers reported that they didn't know how to transfer MT60EM A's data to B's data. After we talked about this problem, we went to the production line immediately to get two machines for video operation and guided customers step by step to operate them. So, here is the solution, as below: Connect machine A's and machine B's green and white wires and power them on. First press 71# on the machine without data to receive, then press 70# on the machine with data to send. If you do it the wrong way, it will not work.   Don't hesitate to get in touch if you need more clarification. If you wanna know more products or require any additional information, pls kindly contact us as below:  S4A INDUSTRIAL CO.,LIMITED Contact Sales: Ms Anna Zhang Tel:+86 755 29450011 EXT: 608 Mob/whatsapp/Viber +86 134 10500721 Skype:crypton0908 Email: sales1@s4a-access.com

In recent years, with the development of technology, smart home has long since bid farewell to the concept, appearing in every corner of the home. For example: sweeping robots, smart speakers, smart TVs, Remote gate controller,infrared switches...There are many kinds of intelligent products, and many times tricks and gimmicks take the place of the role. The core of smart products should be to serve life and facilitate different social roles and occasions.In fact, S4A already has products in the field of smart home, but we have been adhering to the principle of low-key and calm, and have been making products silently without excessive publicity.S4A Automatic Swing Gate Openers is a driver (drive device) composed of intelligent motor, speed change mechanism and nylon silent transmission system.Under what circumstances will an automatic sliding gate openers be used?At first glance, the gate opening kit seems to be far away from us, but in daily life, when you open the door with something in your hand, when you just wash your hands and enter the door, pay attention to the quality of life and enjoy the intelligent experience, especially when the boss wants to open the door (after all, the door If someone opens the door, how can the office door be opened in person)......Of course, it is also a life helper for the elderly and people with limited mobility.In addition to being easy to use, the ED200 and ED300 also have the following features: Which is the stronger opening posture:You can use the remote control to open, the button to open, the radar to open, and even a kick (kick switch)200,000 door opening testsIn other words, if you use it 10 times a day, you can use it for 55 years.1 hour to complete the installationIt only takes 1 episode of American drama to install it and start using it.Back to the original question, why do you want to produce the remote control gate opener? S4A has more than 20 years of experience in the field of access control systems and solutions. Due to the various requirements of users for opening doors, there are automatic swing door openers.What kind of gate opener system is good? How to make the door opener match the door reasonably? Which door type is more suitable for installing a door operator? How to meet the needs of using functions and opening doors at the same time?With these questions, we have done a lot of research and tests to understand the use experience, and only have this S4A ED100,ED200 and ED300 automatic door openerOnly those who do access control know how to open the door.

Our factory has 15 years experience in magnetic lock production.Whether it is the low-end market, the terminal market, or the high-end market, our company has corresponding magnetic locks to meet your different needs.Of course quality is based on cost. mini Magnetic locks should be identified from various technical indicators. Standard qualified magnetic lock door generally provide two input voltages of 12V and 24V (the difference between single coil and double coil) for time delay magnetic lock, They are selected and switched by jumpers. There are several ways to judge the pros and cons of a magnetic lock:Here,S4A company's engineers have summarized 15 related knowledge for your reference.1. Circuit board: The inferior magnetic lock can be judged from the circuit board. The inferior magnetic lock circuit board has rough printing and extremely simple layout. A set of voltage inputs.2. Measure the resistance: first unplug the 12V and 24V switching jumpers of the magnetic lock (note: no power is required), generally there are 4 binding posts (at the jumper), measure the red and black lines, the resistance is at Preferably around 50 ohms.3. Measure the current value after power-on: After the magnetic lock is connected to 12V voltage, the current value is measured, and the one that matches the marked value is better. 280KG (600 lbs) magnetic lock is generally better at 400-450 mA. If it is less than 450 mA, it is not enough to pull; if the voltage is 24V, the marked value or actual value should be 200 mA.4. Insulation value: The insulation value of the lock body of a standard qualified magnetic lock should be infinite, and the specific value should be more than 50 megohms; the specific test position is the cut steel sheet and the output line of the lock body.5. Perpendicularity of the cut steel sheet: In principle, the cut steel sheet should be touched or stained with hands as little as possible. The perpendicularity and parallelism of the qualified magnetic lock cut steel sheet should be as standard as possible. The quality of the electroplating of the cut steel sheet depends on whether there are oxidation marks on the cut steel sheet.6. Glue inspection: There should be no air bubbles in the colloid of the magnetic lock, it should be flat and neat, without cracks, and the angle is square.7. The distance between the cut steel pieces: the main concern is that the thickness of the cut steel pieces should be 0.35mm, which is the best. At present, most of the steel cut pieces on the market use 0.5mm cut steel pieces; the tighter the arrangement of the cut steel pieces on the lock body, the better , Pay attention to observe that there is no glue leakage in the arrangement of the cut steel sheets.8. No residual magnetism: Generally, the cleats of magnetic locks are made of pure iron, but most of the cleats are 99% pure iron, so they must have the function of removing residual magnetism, and are equipped with protruding rubber pads to play a buffering r...
