Turnstiles are access control devices that isolate people in access areas. They can be used to implement simple access control, people counting and – in conjunction with reader systems – access control and prevention of unauthorized access.
Depending on the area of ​​application, turnstiles are available in a wide variety of designs.
In normal operating conditions, an electric brake keeps the starwheel in a locked position. When released by the reader system or an optional external manual control, the brake is released and passage is permitted in the respective direction.

Light pressure triggers the drive and rotates the star by 120° or 240°. Internal sensors prevent injuries caused by the rotating star hitting the person walking through.
After the passage has been completed, the turnstile sends a signal to the reader.
To avoid injuries in the event of panic, a slip clutch allows actuation from 40 kN in the locked state, emitting an alarm signal.

When the power is off, the rotating star can be turned manually with little force.
For operation without control, for passage with bulky items of luggage or for rapid clearing of the area, the rotating star can be moved into a barrier-free, open position in which both bars remain outside the passage area.
