How Revolving Door Achieve Anti-pinch and Anti-collision ?

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 motion. We also call this part as vertical safety switch or horizontal safety switch.

▪  Speed Control & Emergency Stop

The door’s rotation speed is regulated to ensure safe passage. In emergencies, a manual stop button or quick brake system activates instantly.

▪  Warning Signals (Visual/Audio)

Lights or beepers alert users if the door is about to move or if an obstruction is detected.

Key Safety Standards. Compliance with EN 16005 (EU) or ANSI /BHMA A156.10 (US) ensures reliable anti-pinch and anti-collision performance.
