The speed gate turnstile is with high-quality servo motor is configured and advanced servo control system is carried to truly achieve precise control, stable performance with no maintenance. Lossless mechanism structure is based on German technology adopted to ensure long lifespan. The matrix type photoelectric stereoscopic detection technology is adopted to sensitively detect the behaviors that threaten the passageway safety, such as illegal intrusion, reverse passing, tail-gating, and give out alarms through sound, light, etc. The turnstile can be combine with other security systems. CQL1000SG is the column speed gate turnstile, with LED indicator for access status. Transparent optical glass, support carved logo on the swing. The reader and control part is independent of the speed gate, they can install on the wall or extend tail column. The CQL1000SG speed turnstile gate can work one side alone or work as pair.
