The Role of Circuit Boards in Automatic Door Systems: From PCBA to EMS
Automatic doors are a common sight in shopping malls, office buildings, and hospitals, offering convenience and accessibility. But have you ever wondered how these doors operate so smoothly? The secret lies in their electronic control systems, where circuit boards (PCBA) play a crucial role.
Do All Automatic Door Systems Need a Circuit Board?
The short answer is yes. Modern automatic door systems rely on electronic control mechanisms to detect movement, manage motor operations, and ensure safety. While very basic sliding doors might use purely mechanical systems, most commercial and industrial automatic doors require an automatic door controller, which is built around a printed circuit board assembly (PCBA).
Where Are Circuit Boards Used in Automatic Door Systems?
1. Automatic Door Control Board (Main Controller)
- This is the brain of the system, processing signals from sensors (like motion detectors or safety beams) and sending commands to the motor.
- It ensures smooth opening/closing, speed adjustment, and emergency stop functions.
- High-end models may include programmable logic for different operational modes.
2. Sensor Modules
Infrared, microwave, or laser sensors often contain small PCBAs to process detection signals before sending them to the main controller.
3. Motor Drive Unit
The motor that moves the door is controlled by a drive circuit board, regulating power and direction.
4. Safety and Backup Systems
Emergency stop mechanisms and battery backup circuits also rely on PCBAs for reliable operation.
The Importance of EMS in Automatic Door Manufacturing
Electronics Manufacturing Services (EMS) providers play a key role in producing high-quality automatic door control boards. They handle:
- PCB design and assembly (PCBA)
- Component sourcing and testing
- Firmware programming
- Durability and environmental testing (since automatic doors must work in varying temperatures and conditions)
A well-designed PCBA ensures long-term reliability, energy efficiency, and compliance with safety standards like EN 16005 or ANSI/BHMA A156.10.
Conclusion
From motion detection to motor control, circuit boards are essential in automatic door systems. The automatic door control board acts as the central hub, while sensor and drive modules rely on smaller PCBAs. With the support of EMS providers, manufacturers can ensure robust, efficient, and safe automatic door operations for years to come. TECOO is a professional EMS company. Come and contact us.
