| 2 | Finish | Brushed or polished, smooth edges, vandal-resistant design | Aesthetic finish that hides scratches and prevents injury; resists damage from tampering. |
| 3 | Barrier Type | Swing arm / flap panel / retractable wings (as specified) | The moving part controls access; type chosen based on speed, aesthetics, and security needs. |
| 4 | Body Thickness | Minimum 1.5 mm (main housing panels), can be 2.0mm or above. | Thicker panels resist dents, impacts, and vandalism, increasing product life. |
| 5 | Ingress Protection Rating | IP54 (indoor) / IP65 (outdoor) | Indicates dust and water resistance; ensures operation in various environments. |
| 6 | Lane Width | Standard: 550–600 mm; Wide: 850–1,000 mm | Determines passage space; wide lanes accommodate wheelchairs (ADA/DAA compliance), trolleys, and luggage. |
| 7 | Housing Dimensions | Approx. 1,200–1,500 mm (L) × 150–300 mm (W) × 980–1,050 mm (H) | Defines gate size for installation planning and space management. |
| 8 | Motor Type | Brushless DC or servo motor | Provides smooth, silent, and low-maintenance operation; suitable for high-traffic use. |
| 9 | Opening / Closing Time | Adjustable 0.3–1.0 seconds | Speed of gate movement; adjustable to match security or convenience needs. |
| 10 | Operation Modes | Bi-directional / uni-directional / free passage / controlled passage | Allows flexible access control for entry, exit, or special event modes. |
| 11 | Locking Mechanism | Electromagnetic or mechanical locking with fail safe/fail secure option | Secures barrier in position; fail-safe opens during emergencies, fail-secure keeps locked. |
| 12 | Sensors – Safety | Minimum 4–8 pairs of infrared sensors | Detects movement and prevents unauthorized entry or accidents. |
| 13 | Anti-Tailgating | Alarm & auto re-close | Prevents unauthorized users from following an authorized person. |
| 14 | Anti-Pinch | Automatic stop/reverse on obstruction | Prevents injury by reversing barriers if blocked by an object/person. |
| 15 | Emergency Mode | Auto-open or retract during power failure or fire alarm | Ensures safe evacuation during emergencies. |
| 16 | Access Control Integration | Compatible with RFID, biometric, QR, barcode, NFC, facial recognition | Works with existing or future security systems for identity verification. |
| 17 | Communication Interface | TCP/IP, RS485, dry-contact relay | Enables connection to building management and security systems. |
| 18 | Status Indication | LED direction arrows, status lights, and/or LCD display | Guides users clearly on whether passage is allowed or denied. |
| 19 | Power Supply | 100–240 V AC, 50/60 Hz | Supports global electrical standards for easy installation. |
| 20 | Power Consumption | Standby ≤ 20 W; Operation ≤ 60–120 W | Low energy use reduces operational costs. |
| 21 | Battery Backup | Optional UPS for uninterrupted operation | Keeps the system running during power cuts for security continuity. |
| 22 | Throughput Capacity | 30–50 persons/minute (controlled); up to 60 in free-flow | Handles large crowds efficiently during peak times. |
| 23 | MTBF | ≥ 5 million cycles | Indicates reliability and lifespan before failure. |
| 24 | Operating Temperature | -20°C to +60°C (outdoor with optional heater based on region) | Allows operation in extreme weather conditions. |
| 25 | Certifications | CE, RoHS, ISO 9001; Safety: EN 61000, IEC 60529, IP54/ IP55/ IP65 test report from accredited lab. | Confirms compliance with safety, quality, and environmental standards. |
Optional value added features for turnstile gates etc. (definitions & use)
| No. | Feature | Description | Definition & use |
| O1 | Integrated Payment System | Card or mobile wallet integration for paid access areas | Ideal for gyms, transport, or paid events; enables automated entry fee collection. |
| O2 | Advanced Display | 7–42″ LCD or holographic welcome/guidance screen | Enhances user experience with instructions, branding, or real-time messages. |
| O3 | Branding Panels | Custom logo or advertising space on gate housing | Promotes corporate identity or revenue generation through ads. |
| O4 | IoT Connectivity | Cloud monitoring & remote diagnostics | Enables remote maintenance alerts and usage analytics. |
| O5 | High-Security Mode | Dual authentication (e.g., card + biometric) | Increases access security for sensitive areas. |
Technical specifications for turnstile gates are very important for every site, and may vary based on needs and applications.
