  The core differences between infrared radars and microwave radars used in   automatic sliding doors   lie in their induction principles, applicable scenarios, anti-interference capabilities, etc. The specific comparisons and characteristics are as follows. I. Differences in Induction Principles ▪  Infrared Radar operates based on infrared reflection detection and is divided into active and passive types. Active infrared sensing is commonly used for automatic doors. The sensor emits infrared rays of a specific wavelength. When a human body or object enters the sensing range, it reflects the infrared signal. The receiver detects changes in the reflected signal (such as signal intensity and reflection angle), determines the presence of a moving object, and then triggers the door to open. Essentially, it detects "the reflection of infrared rays by objects" and has weak ability to sense stationary objects. ▪  Microwave Radar works based on the Doppler effect and us...

  The core difference between active radars and passive radars lies in whether they actively transmit detection signals. The two vary significantly in working principles, performance characteristics and applicable scenarios, with specific comparisons and analyses as follows.  I. Core Working Principles ▪  Active radar operates in a "active transmission + receiving reflected signals" mode. The radar itself emits electromagnetic waves (such as microwaves, infrared rays, etc.), which cover a preset detection range. When a target object appears within the range, the electromagnetic waves are reflected back to the radar receiver. By analyzing parameters like time difference, frequency offset and signal intensity of the reflected signals, the receiver determines the target’s position, distance and moving speed, and triggers corresponding actions (like automatic door opening). In the automatic door field, active infrared sensing radars and 24GHz microwave radars fall into this c...

  About the   automatic folding door TAF100S , bi-parting (double-opening type), total 4 door leaves (2 leaves for each side), the core operating mechanism lies in motor drive + synchronous transmission + sensor signal feedback. It realizes the synchronous folding, opening and closing of door leaves through the linkage of mechanical structures, while cooperating with the control system to ensure safe and stable operation. The detailed operation process and core component principles are as follows . I. Core Components Drive System ▪   Main Drive Motor . DC brushless motor is usually adopted, installed in the top drive boxes of door frames on both sides to provide power for door leaf movement. They feature speed regulation and self-locking functions to prevent door leaf slippage when power is off . ▪   Transmission Gears/Timing Belts . Connect the motor output shaft with the door leaf linkage mechanism, converting the motor’s rotary motion into the linear + f...

  The   full-glass /all-glass /crystal 3/4-wing revolving door   is a high-end entrance and exit device that combines full-glass transparent design with a 3/4-wing high-efficiency passage structure. It integrates aesthetics, practicality and safety, and is widely used in high-end commercial and public building scenarios. I. Core Technical Features ▪   Structural Design Advantages 3/4-wing layout: The 3/4-wing type has a larger gap between door leaves and higher passage efficiency. Meanwhile, it retains the windproof, dustproof and sound insulation performance of revolving doors, effectively maintaining a constant temperature environment inside the building and reducing air conditioning energy consumption. Full-glass frameless/narrow-frame design: Door leaves and frames are mostly made of tempered glass or laminated glass, combined with aluminum alloy narrow frames or frameless structures. It features strong visual transparency, can perfectly adapt to the minimal...

 Folding Door is the type of door which opens by folding door leaves or so-called door panels, and closes by unfolding the door leaves. It is an ideal type of door which is suitable for door areas with limited space. When a folding door is fully opened, it occupies the minimum space and could provide maximum opening width.  TAF100S is the automatic folding door, slim type with 4 folding door leaves (2 leaves for each side), mainly used for the door area inside the building. It could assemble one or two motors (one for single parting and two for bi-parting ), aluminum alloy door frame and tempered glass, integral structure with surrounding doorcase, seamless connection. The smooth door body automatically opens and closes could provide a comfortable and safe passage space, with sound insulation, anti-pinch function and force sensitive system. ▪  Electronic System /Operator TAF100S adopts a highly integrated design, innovatively integrating 3 core components including the m...

  The airtightness of   medical airtight doors   (such as the doors in hospital CT rooms, operating rooms, ICUs) is achieved primarily through the sealability of structural design combined with the cooperation of special sealing components, as well as the door's driving and compression mechanisms. When the door is closed, a closed airtight space is formed to prevent air convection, dust or pathogen transmission. Its realization involves three core modules door body structure, sealing components, and driving & compression system, detailed as follows . I. Core Sealing Structure Design 1. Matching Structure of Door Body and Door Frame ▪ Step-type/zigzag interlocking structure. The door body and door frame adopt a concave-convex interlocking step-type design instead of flat direct splicing. When closed, it forms multiple physical barriers to reduce the path of air infiltration through gaps. For example, a flange is set on the inner side of the door frame, and a correspond...
