The turnstiles are easy to use with pictograms for intuitive operation and high throughput. Inactive arms do not obstruct passage, and a shock absorber ensures smooth operation. An optional controlled dropping arm is available for emergencies or power failures.

Flexibility
Removable end covers allow for easy integration of user authentication devices. A wide range of adjustable operating parameters caters to specific functional requirements. The turnstiles are suitable for outdoor installations and offer various options for optimal installation.

Reliability
The housing is made of superior-quality stainless steel, ensuring long life and high reliability with a Mean Cycles Before Failure (MCBF) of 5 million cycles. The turnstiles have a low cost of ownership and low energy consumption, contributing to a low carbon footprint.
