Grey Pearl (Triple Cross)

Basic knowledge of Grey Pearl (Triple Cross):
The Grey Pearl (Triple Cross) manipulator includes a small gear and an energy source component that rotates or drives the small gear in the opposite direction of the electric door opening and closing cycle. Also provided is a gear sector component that rotates in the opposite direction to the rotation of the small gear. The gear sector component of the electric telescopic door can be connected to a small gear and driven by the small gear, so that it rotates in one of the opening and closing directions of the small gear rotation. Provide a thermal protection device to help the control system distinguish between high current at the beginning or end of the door stroke. At the initial time, the peak time is within a few milliseconds, and at the end of the motion, it is within a few hundred milliseconds, which will cause a thermal effect that can excite a bimetallic switch.
