The Swing Type Turnstile Barrier Gate by NIRIKHON (Model NK-ST0021) features a reinforced SUS304 stainless steel body for maximum structural durability. With operating speed under 0.3 seconds and pass rate up to 30 persons/min, it ensures fast, high-throughput pedestrian flow. Five pairs of IR sensors deliver reliable anti-tailgating protection, while IC/RFID/biometric integration and automatic emergency release ensure secure, audit-ready institutional access control.
Built from a 1.2mm SUS304 stainless steel cabinet with a hairline finish and reinforced by a 2.0mm SUS304 internal structure, the housing shields all internal drive and control components from tampering, corrosion, and continuous mechanical stress. This chassis forms the structural backbone of the NK-ST0021, ensuring the unit holds its form and function through years of high-frequency institutional operation.
A high-performance DC brushless motor drives the swing-arm transmission with low-noise, low-vibration precision, executing full barrier cycles in 0.3 seconds or less. This drive mechanism is engineered for durable, high-cycle service life, sustaining a pass rate of 30+ persons per minute without mechanical fatigue or performance drift.
The onboard integrated controller board governs credential verification, motor actuation, and sensor input in real time, functioning as the operational core of the access decision process. A manual override button is built directly into the enclosure, giving on-site personnel immediate physical control during emergencies or system maintenance.
Five pairs of infrared sensors form a continuous detection field across the pass lane, identifying unauthorized tailgating attempts and preventing simultaneous multi-person passage on a single credential. The same sensor array delivers anti-pinch protection, halting arm movement the instant an obstruction is detected within the pass zone.
The transparent acrylic swing arm combines physical obstruction with embedded LED lighting, delivering both a visible security boundary and immediate illuminated status feedback at the point of passage. Its swing-arm geometry enables rapid, wide-clearance cycling suited to high-throughput checkpoints without sacrificing structural resistance to forced entry.
A clearly visible three-color LED array — green for access granted, blue for standby, and red for access denied — gives personnel and monitoring staff instant, unambiguous visual confirmation of gate status. This guidance layer reduces entry hesitation and supports faster, more orderly pedestrian flow at controlled checkpoints.
This integration hub unifies IC, RFID, QR, and facial recognition credentialing into a single verification pathway, allowing the gate to process diverse identity formats without hardware duplication. Card and biometric reads are verified in under 0.2 seconds, keeping multi-factor authentication fast enough to sustain uninterrupted pedestrian throughput.
Gives operators a live, centralized view of every gate's passage activity and access status across the network.
The NK-ST0021 is engineered with an automatic emergency power-failure release mechanism. In the event of a power interruption, the barrier arm automatically unlocks, allowing unobstructed evacuation without requiring manual intervention — ensuring continuous compliance with emergency egress protocols.
Anti-tailgating enforcement is handled by a 5-pair infrared sensor array positioned across the pass lane. This configuration continuously monitors for simultaneous or unauthorized multi-person passage on a single credential, while the same sensor field provides anti-reverse entry and anti-pinch detection to maintain both security integrity and personnel safety.
Yes. The platform includes a lifetime SDK and open API license at no additional cost, enabling direct integration with third-party identity databases, surveillance platforms, and centralized command systems. Communication is supported over RS485 and TCP/IP interfaces for network-wide coordination.
The platform supports a database of up to 30,000 registered users and retains up to 100,000 access log records, with credential verification processed in under 0.2 seconds and a sustained pass rate of 30+ persons per minute — supporting high-traffic checkpoints without throughput degradation.
The gate housing is constructed from 1.2mm SUS304 stainless steel with a hairline finish, reinforced internally by a 2.0mm SUS304 structural frame. This construction is designed to withstand sustained mechanical stress and continuous daily cycling typical of high-security institutional facilities, backed by a 1-year device warranty.
