Barrier Gate Dual Channel Loop Sensor | High Accuracy & Wide Temp Range & Direction Logic

Barrier Gate Dual Channel Loop Sensor | High Accuracy & Wide Temp Range & Direction Logic

The JUTAI Barrier Gate Dual Channel Loop Sensor (Models LD-200/LD-202) is engineered to deliver unmatched precision and reliability for automated barrier systems in high-traffic environments. Featuring dual-channel independent control, it ensures high-accuracy vehicle detection with 16-level sensitivity adjustment (0-F) across a 20–2000μH inductance range, capturing everything from motorcycles to heavy trucks. The sensor’s advanced direction logic utilizes time-sequence analysis to determine vehicle entry/exit direction with <1-second latency, enabling intelligent barrier control in parking lots, toll lanes, and secure facilities. Built to endure extreme conditions, the IP67-rated aluminum housing operates flawlessly in a -40°C to +70°C temperature range, resisting dust, moisture, and corrosive elements for year-round reliability.

In smart parking systems, the LD-202’s direction logic prevents tailgating by triggering barrier closure only after confirming vehicle clearance, while Channel 1 ensures rapid gate opening (≤10ms response). For industrial gate control, the sensor’s wide temperature tolerance maintains stable performance in freezer warehouses or desert sites, and its 40–80KHz anti-crosstalk technology blocks interference from nearby detectors or EV chargers. A recent deployment at a Middle Eastern logistics park reduced unauthorized access by 40% through real-time directional monitoring. The sensor’s universal 12-24V DC/100-240V AC input supports solar and grid power, while SPDT relay outputs integrate seamlessly with barrier controllers, license plate recognition systems, and IoT platforms for centralized management.

JUTAI prioritizes ease of deployment and compliance: plug-and-play DIN-rail mounting reduces installation time to 15 minutes, and auto-reset functionality ensures uninterrupted operation during voltage fluctuations. Certified for CE, FCC, and RoHS, it meets global safety and environmental standards. Backed by a 5-year warranty and 24/7 technical support, the JUTAI Dual Channel Sensor is the definitive choice for engineers seeking durability, precision, and intelligent barrier control—where cutting-edge direction logic meets industrial resilience.
