BurookHi Norman... I just remembered i didn't let u know.... everything worked out we made both the wired and the remot control opening work... they loved the item (assuming it will hold its own for the next 10 years or so) -
KiranYes I don’t doubt you. Jutai is one of the most confident companies I came across in China

Product Description
Loop Detector LD Series: Single And Dual Channel With High Sensitivity & Weatherproof Housing
JUTAI LD Series loop detectors (single-channel LD100/LD102 and dual-channel LD200/LD202) are industrial-grade vehicle detection solutions engineered with high sensitivity and weatherproof housing, tailored for harsh outdoor and indoor applications including parking management, traffic control, and industrial door automation. This series combines adjustable precision sensing with rugged durability, delivering reliable performance in rain, dust, extreme temperatures, and high-traffic environments.
Product Range
- Single-Channel Models (LD100 AC / LD102 DC): Equipped with 16-level high sensitivity adjustment, ideal for basic presence/pulse detection scenarios like gate activation and single-lane sensing.
- Dual-Channel Models (LD200 AC / LD202 DC): Features 8-level independent high sensitivity per channel + directional detection, designed for advanced use cases such as entry/exit counting and bidirectional traffic monitoring.
All LD Series detectors boast IP-rated weatherproof housing, ensuring protection against water, dust, and corrosion—critical for outdoor deployments in parking lots, roadways, and industrial yards.
Key Features
- High Sensitivity Precision: Single-channel models offer 16-level sensitivity tuning (0.015%-0.8% DL/L); dual-channel models provide 8-level independent adjustment per channel.
- IP-Rated Weatherproof Housing: Rugged, sealed housing protects against water ingress, dust accumulation, and corrosion.
- Dual Channel Directional Detection (LD200/LD202 Exclusive): 3 configurable direction modes accurately identify vehicle travel direction.
- Industrial-Grade Durability: Wide operating temperature range (-40°C to +70°C) and 95% non-condensing humidity tolerance.
- Anti-Interference Design: 4-step selectable frequency eliminates cross-talk with adjacent loops.
- Easy Configuration & Integration: DIP switch control for sensitivity, frequency, and operating modes.
- Real-Time Status Monitoring: LED indicators for power, detection status, and loop faults.
