In recent years, entrance automation has become a common trend in hospitals, office buildings, shopping centers, and many public facilities. The application of automatic doors not only enhances user convenience but also improves safety, hygiene, and the professional image of a building. Compared to traditional swing doors, automatic doors overcome several limitations such as the need for direct hand contact—particularly inconvenient in medical environments—difficulty of use for the elderly, people with disabilities, or wheelchair users, and the risk of collisions during peak hours. Driven by these practical needs, NABCO automatic swing doors are increasingly being chosen by investors and facility operators. So, what is an NABCO automatic swing door, how does it operate, and why is this solution so widely adopted in modern buildings? All of these questions will be answered in the following article.
What is an NABCO automatic swing door?
Definition of an automatic swing door
An automatic swing door is a door with a hinged swing structure (single-leaf or double-leaf) that is integrated with a motor and control unit to automatically open or close when receiving signals from activation devices such as sensors, push buttons, or remote control systems.
The basic operating principle of an automatic swing door is as follows:
- When the system receives a signal (human detection, push button, access card, etc.), the motor activates the arm or folding arm to open the door leaf.
- After a preset holding time, the door automatically closes.
- Safety sensors allow the door to stop or reverse if an obstacle is detected.
Compared to automatic sliding doors, automatic swing doors offer advantages in locations with limited lateral space or where existing door structures need to be retained.
What is an NABCO automatic swing door?
An NABCO automatic swing door is a swing door system manufactured by NABCO (Japan). The brand is well known for its high durability, stable operation, and ability to meet strict standards in medical and public environments. NABCO is a leading global automatic door brand with a long development history and presence in many countries. NABCO doors are widely used in:
- Hospitals and healthcare facilities
- High-end office buildings
- Hotels and shopping centers
- Factories and industrial zones
With Japanese technology as its foundation, NABCO automatic swing doors are highly regarded for their precision, safety, and long service life, making them especially suitable for buildings that require continuous operation.
Why are automatic swing doors widely used?
Automatic swing doors—especially NABCO products—are favored for their ability to solve space and accessibility challenges.
- Suitable for limited spaces: Unlike sliding doors that require long tracks and wall space, automatic swing doors only need standard swing clearance, making them ideal for small entrances and narrow corridors.
- Accessible for all users: Smooth, automatic opening allows wheelchair users, people using crutches, and those carrying heavy items to pass through easily without physical effort, meeting ADA accessibility standards for public buildings.
- Reduced hand contact, improved hygiene: With sensors or touchless activation buttons, automatic swing doors help prevent cross-contamination—an ideal entrance solution for hospitals, clinics, and high-traffic areas.
- Flexible applications: Suitable for single or double doors, and compatible with wood, aluminum, steel, and glass doors, allowing easy upgrades to existing door systems. The system can also integrate with access control, card readers, fingerprint scanners, interlock systems, and fire alarm systems.
Structure and operating principle of NABCO automatic swing doors
Door system components
To fully understand what is an NABCO automatic swing door from a technical perspective, it is essential to examine its core components. The system is compactly designed and integrates multiple elements to ensure stable and safe operation. A typical NABCO automatic swing door system includes:
- Motor and control unit: The heart of the system, ensuring precise, smooth, and long-term operation. The motor provides rotational force, while the controller processes signals, adjusts opening/closing speed and force, and manages safety functions.
- Drive arm/folding arm: Transfers force from the motor to the door leaf. Two main types are used: standard push arms and pull-type folding arms, depending on installation orientation.
- Activation devices: Depending on usage needs, the door can be activated by sensors, elbow push buttons, foot switches, touchless switches, or access control systems.
- Door leaf and hinges: Existing doors can be reused or replaced with new ones, compatible with various materials such as wood, steel, or aluminum glass. Traditional hinges create the rotation axis.
Operating principle
The operating principle of NABCO automatic swing doors is optimized to ensure safety, smoothness, and precision—key factors that distinguish NABCO from other products on the market.
- Signal detection: When a user enters the sensor detection zone (or presses a button / waves a hand), the controller receives the signal.
- Motor activation and door opening: The controller calculates the required force and speed, powering the motor accordingly. The motor transfers force through the drive arm, causing the door to swing open in the programmed direction. NABCO’s strength lies in its smooth acceleration and deceleration control, minimizing vibration.
- Safe closing and obstacle detection: The door remains open for a preset time (typically 3–10 seconds), then closes gently at a controlled speed. If safety sensors detect an obstacle such as a person or trolley, or if abnormal resistance is detected, the door immediately stops and reverses, then attempts to close again at a slower speed.
Types of NABCO automatic swing doors and practical applications
NABCO offers various automatic swing door models with different capacities and features to meet diverse market needs. Examining real-world applications helps clarify what is an NABCO automatic swing door in different environments.
Automatic swing doors for hospitals and clinics
Medical-grade models are commonly used, integrated with touchless push buttons and interlock systems. These doors are installed at operating rooms, X-ray rooms, and clinical corridors, ensuring hygiene and smooth movement of hospital beds and carts. A notable model is the NABCO GT8400 airtight swing door, which combines a specialized motor and door leaf to provide a comprehensive solution for areas requiring strict air control and maximum safety.
Automatic swing doors for office buildings
These doors are suitable for office entrances, meeting rooms, and internal circulation areas. Designed with high aesthetic standards, quiet operation, and seamless integration with card-based access control systems, automatic swing doors enhance security while creating a professional, modern, and comfortable working environment.
Automatic doors for hotels, shopping centers, and airports
These solutions are ideal for high-traffic environments requiring continuous operation and superior user experience. Systems can integrate with multifunction control buttons to support wheelchair users in public areas while meeting aesthetic, durability, and comfort requirements. Applications include entrances to industrial kitchens, service rooms, utility areas, and emergency exits. With high durability and a light manual opening feature, these doors optimize workflow, ensure fire safety compliance, and improve overall operational efficiency.
A standout model in this category is the NABCO GT-20A automatic swing door, which integrates multiple functions into a single motor. It operates reliably even in strong wind conditions and allows flexible switching between maximum power mode and energy-saving mode—well suited for modern buildings.
Automatic swing doors for factories and industrial zones
Automatic swing door solutions for industrial environments meet high requirements for durability, safety, and traffic control. Suitable for clean rooms, laboratories, and inter-production corridors, these systems operate reliably under harsh conditions and integrate with interlock systems to control room pressure. This ensures closed-loop production processes, environmental compliance, and improved operational efficiency.
