Turnstile

Turnstiles are access control devices that create individual passage for people in access areas. With their help, simple access control, person counting, and – in conjunction with reader systems – access control and prevention of unauthorized access can be implemented.
Depending on the area of application, there are turnstiles in various designs.
In normal operating condition, an electric brake holds the rotating star in a locked position. When released by the reader system or an optional external manual control, the brake is released and passage is granted in the respective direction.

With light pressure, the drive is activated and rotates the star an additional 120° or 240°. Internal sensors prevent injuries by stopping the rotating star from colliding with the person passing through.
After passage, the turnstile sends a signal to the reader.
To prevent injuries in case of panic, a slip coupling allows operation from 40 kN in the locked state while emitting an alarm signal.

In the de-energized state, the turnstile can be manually rotated with little force.
For operation without control, for passage with bulky luggage, or for quick clearance of the area, the turnstile can be set to a barrier-free, open position where both beams remain outside the passage area.
