In environments with high electromagnetic interference (EMI) — such as hospitals, airports, and industrial facilities — many customers report that their automatic door operators are prone to malfunction or instability. As an experienced OEM manufacturer of automatic door operators, we understand this concern and have developed targeted solutions to ensure consistent performance even under challenging EMI conditions.
Electromagnetic interference is caused by the presence of strong electromagnetic fields emitted by devices such as:
Industrial machinery
MRI equipment
Radio transmitters
High-voltage lines
These fields can disrupt the signals between the door controller and sensors, leading to issues such as:
Unexpected door opening/closing
Delayed response
Total system failure in severe cases
We address this issue at both the hardware and software levels to guarantee superior stability and reliability.
Our operators use shielded communication cables that block external electromagnetic fields. This prevents signal distortion and ensures accurate data transmission between the controller and sensors.
All control boards are designed with multi-layer PCB structures and EMI suppression filters, reducing susceptibility to noise and interference.
We integrate high-sensitivity sensors with anti-jamming circuits, which allow the system to distinguish between real activation signals and background electromagnetic noise.
Voltage spikes caused by EMI or power fluctuations are neutralized by surge protection modules in the power supply unit, protecting the door operator from damage.
Our control software includes intelligent algorithms that filter out irregular signals caused by electromagnetic interference, minimizing false triggers.
Thanks to these design enhancements, our automatic door operators are ideal for use in locations with high EMI, such as:
Hospitals (MRI/CT scan areas)
Airports (radar equipment zones)
Data centers
Manufacturing plants
In third-party testing and field installations, our door operators have shown over 99.9% operational reliability even in the presence of strong EMI. Clients have reported significantly fewer malfunctions and a marked improvement in stability after switching to our systems.
If you're struggling with automatic doors that fail under electromagnetic interference, our high-performance, EMI-resistant solutions offer the reliability and peace of mind you need. As a trusted OEM manufacturer, we’re committed to delivering products that meet the real-world needs of demanding environments.
