TDOOR_TSTC AUTOMATIC DOORS

  Automatic Revolving Door  is the popular solution for the main entrance of  hotels/resorts ,  shopping malls ,  office buildings , hospital etc., and it's easy for us to see the revolving door wings always stop/start or be locked at the right postion, how does it happen ? Automatic revolving /rotating doors achieve precise positioning of door wings through a combination of sensors, control systems, and mechanical components, it works as below . ▪  Position Sensors Optical or magnetic sensors detect the exact angle and position of each door wing as it rotates. Encoders  (rotary or linear) provide real-time feedback on the door's movement. ▪  Control System (PLC or Microcontroller) A programmable logic controller (PLC) or embedded microcontroller processes sensor data. It adjusts the motor’s speed and direction to ensure smooth and accurate positioning. ▪  Motor & Drive Mechanism A servo or stepper motor (often gear-driven) allows for pre...

  We often see the   automatic revolving doors   in   hotel/resort ,   office building ,   shopping mall ,   airport  and other type of projects, and we find the door wings always stop/start at a fixed correct position, also locked at a fixed position..... It's because of a key electronic part called encoder. Encoder  is the critical component in automatic revolving doors for achieving precise positioning of the door wings. They function as the "eyes" of the control system, providing real-time feedback on the door's rotational movement, which make the revolving door smart. The details are as below . 1. Types of Encoders Used in Rovolving Doors A. Rotary Encoders A-1. Incremental Encoders Generate pulse signals (A, B, and sometimes Z channels) as the motor shaft rotates. The control system counts pulses to determine position and speed. Requires a reference point (homing) at startup since it only tracks relative movement. Example: If the encode...

  Automatic revolving doors   achieve the Anti-pinch/Anti-squeeze and Anti-collision safety features through a combination of sensors, control systems and mechanical design. Please check the part below for details. ▪  Motion Sensors (Infrared/Laser/Radar) The  Sensors  detect obstacles (people, objects) near the doo's rotation path. If an object is too close, the sensors signal the control unit to slow down or stop the door. ▪  Control System /Software We  TSTC automatic revolving doors  compile and use the software to predict movement patterns, adjusting rotation dynamically to avoid collisions, especially in high-traffic areas. The standard ones including torque control system and force sensitive door leaf . ▪  Safety Edges (Pressure-Sensitive Strips) Flexible rubber strips with embedded sensors line the door wings or edge of the door body. If someone is pinched or pushed, the pressure triggers an immediate reversal or halt of the door's mo...

  Automatic Sliding Door   and   Automatic Revolving Door   are the 2 key products and hot sale doors from TSTC Automatic Doors. Do you know the big differences from these 2 type of doors ? Here is the answer as below .  ▪ Automatic Sliding Doors Definition: Doors that open horizontally via motor-driven tracks, commonly used in commercial and healthcare settings. Advantages: Space Efficiency: Ideal for limited spaces; telescopic (foldable) designs maximize opening width while minimizing footprint. Smooth surfaces (stainless steel/glass) resist corrosion and enable easy disinfection. Safety & Accessibility: Force-sensitive reversal stops or reverses upon collision, reducing injury risks. Non-contact operation via sensors/buttons supports infection control. Energy Savings: Rapid closing minimizes air exchange, cutting HVAC costs. Low Noise: PWM-driven motors and silent tracks (<49 dB) suit quiet environments. Disadvantages: Limited Flow Capacity: Smaller op...

  Here's an overview of frequently-used radars /sensors in   automatic sliding doors ,   swing doors   including Microwave Radar, Infrared Radar, Ultrasonic Radar, Light Detected Radar . 1. Microwave Radar Sensors Principle:  Detects motion based on the Doppler effect (frequency shift of reflected waves). Characteristics: Wide detection range (typically 3–10 meters). Works well in various weather conditions (rain, fog, dust). Detects movement only (not suitable for stationary objects). May have false triggers from moving objects outside the intended area. Best for High-traffic areas like  shopping malls ,  airports . 2. Infrared (PIR) Sensors (Passive Infrared, not radar but commonly used alongside) Principle:  Detects body heat (infrared radiation). Characteristics: Energy-efficient (consumes less power than radar). Works best for human detection (not affected by wind or moving objects like curtains). Limited range (usually 1–5 meters). Affected ...

  There are 2 types about the motors for   automatic sliding door , brushed motor and brushless motor, here's a comparison of the advantages and disadvantages of these 2 types of motors . ▪ Brushed Motors Advantages are as below . Simple and low-cost – Fewer components, easier to manufacture. Easy to control – Speed can be adjusted simply by varying voltage. No complex electronics needed – Works with basic DC power supply. Good torque at low speeds – Suitable for applications requiring high starting torque. Disadvantages are as below . Lower efficiency (70-85%) – Energy loss due to friction and brush resistance. Limited lifespan – Brushes and commutator wear out over time. Higher maintenance – Brushes need periodic replacement. Electrical noise – Sparking can cause electromagnetic interference (EMI). Lower speed capability – Friction limits maximum RPM. ▪ Brushless Motors Advantages are as below . High efficiency (85-95%) – No energy loss from brushes. Longer lifespan – No bru...

  About the   Electronic Locks   for   automatic sliding doors , there are 2 key types called bi-stable and single-stable(monostable),here's a clear explanation of the differences between these 2 locks as below . ▪ Bi-stable Electronic Lock Definition: Has two stable states - Locked or Unlocked. State Change: Requires an active electronic pulse (like a button press, valid credential scan, relay signal) to switch from one state to the other (e.g., from Locked to Unlocked, or from Unlocked to Locked). Power Dependency: Maintains its current state (Locked or Unlocked) even during a complete loss of power. It "remembers" its last commanded state. Mechanism: Typically uses a latching relay or a bi-stable solenoid/motor. These mechanisms physically lock into position until actively changed. Common Use Cases: Main entry doors, doors where security must be maintained during power failures (remains locked), or doors that need to stay unlocked during a power failure (rema...

  The   lead lined door   is designed to protect against the x-ray radiation with a lead plate filled inside of the door body as well as a  viewing window with lead glass, this type of door is usually applied to the x-ray room or CT room in hospitals. The normal thickness of the lead plate is about 0.5 to 2.0mm, to TSTC, the recommended thickness of the lead board is 3.0mm for most,  we can also adopt the lead plate with some more thickness, however, considering the big density of the lead, it will bring potential loss to the electronic parts and the mechanical parts of the door, because the door body is much more heavy with the thick lead .
