Vehicle Detection Loop Sensor: Pulse & Presence Modes, Easy Installation with 2-Year Warranty

Core Advantages of the Vehicle Detection Loop Sensor

• Dual Operational Modes: Pulse Mode for momentary vehicle triggers and Presence Mode for continuous monitoring, offering flexibility for access control, parking, and traffic scenarios.
• Tool-Free Easy Installation: Pre-calibrated settings, color-coded wiring, and a step-by-step guide make setup quick—ideal for both professional installers and on-site maintenance teams.
• 2-Year Manufacturer’s Warranty: Backed by a comprehensive 2-year warranty, ensuring peace of mind and long-term reliability for commercial and residential applications.
• Universal Vehicle Detection: 16-level adjustable sensitivity (0.010% to 2.56% DL/L) reliably detects vehicles of all sizes, from motorcycles to heavy-duty trucks, with minimal false triggers.
• Intuitive Status Monitoring: LED indicators for power (red) and detection (green) let users instantly track device performance, while a manual reset button simplifies troubleshooting.
• All-Weather Reliability: Rugged, weatherproof housing (IP-rated) withstands rain, dust, extreme temperatures (-40°C to +70°C), and humidity up to 95% (non-condensing), ensuring year-round operation.
