What is an optical speed gate turnstile?

An optical speed gate turnstile, the upgraded optical swing turnstile, offers contactless operation and fully automates the entry procedure by using motorized opening and closing and optical beam detection. Such access control turnstile does not require user contact to open and close when using motorized barriers. It can achieve fully touchless functionality when combined with temperature sensors, facial recognition software, proximity scanners, or other access control systems.

How to determine the suitable model and quantity?

It is crucial to determine the appropriate number of optical speed gate turnstiles for some projects because they operate in pairs. Meanwhile, it is also important to consider the volume of pedestrian traffic and accessibility for the impaired. Take the speed turnstile gate JDSG-18 as an example, which includes the single-wing type and dual-wing type. For a single-lane pass, two single-wing JDSG-18s are necessary, and for a two-lane passage, two single-wing JDSG-18s are fixed to either side of a dual-wing JDSG-18. In addition, most such touchless turnstiles provide 900 mm-wide broad lanes for impaired access.

What are the differences between an optical speed gate turnstile and an optical swing gate turnstile?
Chassis design: The chassis width of an optical speed turnstile gate ranges from 100 to 180mm, and its length is approximately 1400mm. Its swing arm is constructed of pendulum plexiglass or tempered glass. While an optical swing gate turnstile has a broader chassis, the width is generally about 280mm, and the length is 420 ~1400mm, with the swing arms made of #304 stainless steel or pendulum plexiglass.
Traffic speed: The speed gate optical turnstile opens in 0.3 seconds per time, allows 30~45 people per minute to pass, and has an adjustable speed, making it faster than the swing gate optical turnstile. The speed optical turnstile gate has a memory feature that allows users to swipe cards repeatedly and gain entries. While the swing gate optical turnstile with a lower traffic speed allows only one user to pass at a time as it has no memory function and allows 20~25 people per minute to pass.
Driveway: The speed optical turnstile gate utilizes a directly driven method, combining an encoder with a clutch. The swing arm can get the maximum of the motor’s power due to the high motor transmission efficiency, or the high transmission coefficient. When the swing arm experiences an abrupt external force that causes it to deviate from the zero position, the solenoid valve shuts the gate to stop the force and the encoder directs the swing arm to return to the zero position. The clutch will immediately lock the gate in the event of illegal entry. While the swing optical turnstile gate movement uses sliding friction and the four-wheels-four-grooves principle, it is less effective at transmitting efficiency. The groove and wheel are 90 degrees apart. The grooved wheel will side-switch and rub once with each swing of the swing arm. A fixed mechanism also positions the placement. If the anti-collision device is not placed, the external force will immediately strike the movement or swing arm in the event of an impact, causing the swing arm to deviate from the middle zero position and preventing the two sides from being aligned or synchronized. In the worst case, the swing arm will bend due to improper movement. Illegal entry cannot be locked; it can only sound an alarm.
Limiting way: Swing turnstile gate uses optocoupler signals or proximity switches, which have wide contact areas and inaccurate limits. While the speed turnstile gate limits the position with encoders, which can be precise to 1°

Can optical speed gate turnstile be integrated with 3rd party access control systems?
Yes, it is compatible with a wide variety of access control systems by dry contact. Card pass, fingerprint/handprint reader, face recognition, barcode reader, thermal camera, and token applications can integrate with such access control turnstiles.

What will happen when the power is off and in an emergency situation?
It instantly automatically unlocks for free passage under emergency situations (power outages, fire, etc)

Can it be used indoors and outdoors?
Yes, it is made for indoor or outdoor situations. For all outdoor applications, we use 304 stainless steel to prevent corrosion.

Does it give access to ADA pedestrians?
Yes, it provides a wide lane up to 900mm for the disabled to allow for wheelchairs.
