AUTOMATIC DOOR

AUTOMATIC DOOR(αυτοματες πορτες τιμες)

The limit switches are a common component in automatic doors but can also be seen in other devices or systems.

The basic principle of a limit switch is that a movement generates a contact that serves to stop or warn the automation of something.

In Automatic Doors, it is used to indicate the beginning and end of the door travel and make the motor stop. There are different types of limit switches that we explain below:


Wheel Race Fina ln Head Limit Switch: This is a limit switch with a head normally with a wheel that is pushed to one side or the other depending on the movement of the door. Inside it has 2 contacts and detects which way the door moves, activating one or the other contact.


End of Race Dock End of Spring Career: This mechanism is simpler, 2 micro contactors are placed on each side of the spring, when the spring moves to one side it presses one of the micro contacts and to the other side the other contact.


Valvula reed Magnetic Limit Switch On the door motor plate there are 2 magnetic detectors (reed valves) that when passing near them a magnet causes a contact that the plate interprets to stop the motor. https://garazoportes-rolla.gr/aftomates-portes/
