SHENZHEN JUTAI COMM CO.,LTD. (official site: www.accesssecuritysolution.com) — a trusted provider of access security solutions — presents the LD series loop detectors (models: LD-100/102/105/106; LD-200/202/205/206), engineered to outperform standard loop detectors in China. Below is a detailed comparison of JUTAI LD series with mainstream Chinese alternatives (Red loop detector, PD-132):
JUTAI LD Series vs. Generic Chinese Loop Detectors: Key Specification Comparison
| Feature | JUTAI LD Series | Red Loop Detector | PD-132 |
|---|---|---|---|
| Working Power | 110V-240VAC / 12V-24VDC | 110VAC/240VAC/12VDC/24VDC | 110VAC/240VAC/12VDC/24VDC |
| Loop Inductance | 20-2000μH (wider range for diverse scenarios) | 50-300μH (narrow application scope) | 50-300μH (limited compatibility) |
| Core Functions | Auto-restart + Coil fault detection | No additional functions | No additional functions |
| Sensitivity Adjustment | 16 selectable levels (0.008% ΔL/L to 2.50%) | 3 increments (limited precision) | 3 increments (limited precision) |
| Operating Temperature | -40°C to +70°C (extreme weather compatible) | -20°C to +65°C (narrow range) | -20°C to +65°C (narrow range) |
| Component Quality | Taiwan & Japan components (high durability) | Made in China (lower robustness) | Made in China (lower robustness) |
| Warranty | 2 years (long-term after-sales support) | No warranty | No warranty |
| Application Scenarios | Industrial doors, barrier gates, roller shutters, traffic intersections, parking billboards | Roller shutters, barrier gates (limited use) | Roller shutters, barrier gates (limited use) |
| RFID Interference | No (compatible with 125kHz RFID readers) | Yes (interferes with access systems) | Yes (interferes with access systems) |
| Vehicle Compatibility | Small cars, motorcycles, trucks, diverse models | Small cars only | Small cars only |
| Reaction Speed | 1sec (smooth traffic flow) | 3sec (delayed response) | 3sec (delayed response) |
| Lightning Protection | 4000V (enhanced safety) | No | No |
Real-World Application Scenarios of JUTAI LD Series
-
Large-Scale Industrial Park EntrancesA steel manufacturing park in northern China (temperatures drop to -35°C in winter) uses JUTAI LD series for barrier gates. Its -40°C operating range ensures stable detection of trucks (up to 20 tons) and motorcycles, while the 16-level sensitivity avoids false triggers from nearby metal structures. Generic detectors failed here due to narrow temperature and vehicle compatibility.
-
Mixed-Traffic Parking Lots (Shopping Malls)A shopping mall in Guangzhou integrated JUTAI LD series with 125kHz RFID parking systems. The detector’s no-RFID-interference design ensures seamless access for cars, delivery trucks, and electric motorcycles — unlike generic models that caused RFID reader malfunctions.
-
High-Altitude Traffic Intersections (Tibet)A traffic management project in Tibet (frequent lightning storms) deployed JUTAI LD series for vehicle detection. Its 4000V lightning protection and wide temperature range (adapted to +68°C summer heat) outperformed generic detectors that failed after 2 months of use.
Why JUTAI LD Series Stands Out for Your Projects
For parking access control, industrial gate automation, or traffic management systems, JUTAI LD series delivers:
- Broader compatibility for mixed-vehicle scenarios
- Precise sensitivity to reduce false triggers
- Durable components for extreme environments
- Seamless integration with RFID access systems
- Faster response to optimize traffic efficiency
