A full‑height turnstile (full‑enclosed rotor turnstile) is a maximum‑security heavy‑duty pedestrian barrier within a complete turnstile gate system. Unlike half‑height turnstile which only reaches waist height, it adopts full‑height enclosed rotating rotor structure around 2.1‑2.4 m high, delivering robust anti‑climb and anti‑crawl physical protection. It enables reliable unattended perimeter access management and supports one‑way or bi‑directional access configuration, compatible with RFID card, QR‑code, fingerprint and facial‑recognition credential readers. Sintronic full‑height turnstiles have been deployed for overseas access‑control projects including Kuwait and Saudi Arabia pedestrian‑gate reference projects。

Core Working Principle of Full‑Height Turnstile

Sintronic full‑height turnstile follows maximum‑security unattended‑access workflow: Credential Validation → Signal Input → Rotor Unlock → Controlled Rotation for Passage → Auto‑Reset & Anti‑Reverse‑Lock. Full‑cycle operation steps are described as follows.

1. Standby locked status

Under normal standby condition, the enclosed full‑height rotor stays mechanically locked by anti‑reverse clutch assembly, forming complete physical barrier against climbing‑over, crawling‑through and reverse‑direction forced intrusion. Position sensors keep monitoring rotor rotation angle. LED indicator shows red light and waits for valid authorization signal.

2. Credential verification & signal input

Pedestrians present valid credentials: RFID IC card, QR‑code, fingerprint or facial recognition. After identity validation passes, external reader sends Wiegand or dry‑contact signal to full‑height turnstile main‑control board.

3. Mechanism unlock and controlled rotor rotation

Upon receiving valid pass signal: ‑ Semi‑automatic model: Solenoid lock releases; pedestrian pushes the heavy‑duty enclosed rotor to rotate fixed angular displacement for passing. Anti‑reverse clutch blocks backward rotation during movement. ‑ Fully‑automatic model: Built‑in brushless DC motor drives rotor to rotate automatically without manual pushing, with anti‑reverse clutch always active to forbid reverse‑direction forcing.

4. Position‑sensing and anti‑intrusion monitoring

Built‑in position‑feedback sensors continuously track rotor movement angle and rotation direction during passage. If abnormal reverse‑force or forced‑intrusion attempt is detected, control board triggers locking and audio‑visual alarm to deter tailgating, piggy‑backing or break‑in behaviour.

5. Automatic rotor reset and return to locked standby

After completing full valid rotation cycle, position sensor confirms pedestrian passage completion. The rotor automatically resets and re‑locks with anti‑reverse clutch engaged. LED turns back to red and turnstile returns to standby for next user.

6. Emergency power‑off safety function

When main power supply fails, built‑in fail‑safe mechanism activates. The rotor releases into free‑rotating state, allowing free pedestrian evacuation, complying with public‑building fire‑safety requirements.
