| Product List |

The industrial dual loop detector (models LD200/LD202) is a professional-grade automation core tailored for high-speed doors and industrial separation control scenarios. It integrates dual independent detection channels, precise direction judgment, and anti-interference performance, specifically adapting to the high-frequency opening/closing, fast vehicle flow, and strict safety requirements of industrial environments.
This detector not only realizes automatic triggering of high-speed doors but also achieves accurate separation control of personnel and vehicles, bidirectional traffic management, and anti-collision protection—making it essential equipment for warehouses, logistics parks, factories, and loading docks.
| Parameter | Specification |
|---|---|
| Product Name | Industrial Dual Loop Detector |
| Models | LD200 (100-240V AC) / LD202 (12-24V DC) |
| Channels | 2 Independent (directional detection or separate use) |
| Power Supply | 100-240V AC (LD200) / 12-24V DC (LD202) |
| Direction Detection | 3 specialized modes (configurable via DIP switches) |
| Operating Modes | 3 direction modes + 3 normal modes (presence/pulse output) |
| Sensitivity | 8-level per channel (0.015%-0.8% DL/L) |
| Frequency Range | 20-100 kHz (4-step selectable) |
| Response Time | 10-90 ms (on/off) |
| Relay Output | 2 Relays (1 per channel: COM + NO) |
| Loop Inductance | 20-2000 µH per channel |
| Recommended Loop Turns | 3-4m (6 turns) / 4-6m (5 turns) / 6-10m (4 turns) / 10-20m (3 turns) / ≥20m (2 turns) |
| Operating Temperature | -40°C to +70°C |
| Humidity Tolerance | Up to 95% RH (non-condensing) |
| Warranty | 2-year manufacturer's warranty |



Sensitivity and frequency adjustment is facilitated through 7-way and 10-way DIP switch settings. Users can choose from 8 different sensitivity settings by configuring the DIP switch positions according to the provided tables.



The Direction Recognition Function ensures the double channel loop detector does not trigger the signal again when the car passes another UHF reader, thereby recording only the entry or exit records in the system.

The JUTAI LD-200/202 Double Channel Loop Detector can also function as two independent single-channel loop detectors. This configuration is suitable for standard one-in and one-out parking lots, where there is one barrier and one long-range reader at both the entrance and exit.
