Compact, Reliable Vehicle Detection for Industrial and Residential Applications The ULTRA II Vehicle Loop Detector by EMX Industries offers a powerful, compact solution for efficient vehicle detection in diverse settings. With its detachable 7-pin screw terminal and ULTRAMETER™ display, setup and calibration are straightforward, making it ideal for both residential driveways and commercial access control. The detector’s fail-safe operation and automatic sensitivity boost (ASB) ensure precise and reliable detection, even for high-bed vehicles. Key Features ULTRAMETER™ Display: Visual guide for optimal sensitivity calibration with 10 levels of adjustment. Fail-Safe and Fail-Secure Modes: Maintains operational reliability during power loss or loop failure. Automatic Sensitivity Boost (ASB): Enhances sensitivity after initial detection to prevent dropout for high-bed vehicles. Multi-Frequency Settings: Four frequency options to prevent crosstalk in multi-loop setups. Surge Protection: Protects loop circuitry from lightning strikes and electrical surges. Energy Efficiency: Operates at a low 18 mA, reducing power consumption. Technical Specifications Power Supply: 12-24 VDC/AC Current Draw: 18 mA max Dimensions: 3″ x 0.9″ x 2.75″ (76 mm x 22 mm x 70 mm) Operating Environment: -40°F to 180°F (-40°C to 82°C), 0-95% relative humidity Loop Inductance: 20-2000 μH Connection: 7-pin screw terminal Conclusion The ULTRA II Vehicle Loop Detector combines advanced technology with robust construction, making it an excellent choice for secure vehicle detection. Its ULTRAMETER™ display simplifies setup, while the automatic sensitivity boost (ASB) and multi-frequency options ensure precise detection without interference. Designed to operate in extreme temperatures and equipped with fail-safe functionality, this detector is reliable in any environment. Data Sheet Owner's Manual
