EMX ULT-MVP-2 Ultra-Mini-Voltage Loop Detector

The ULTRA-MVP-2 Two Channel Multi-Voltage Vehicle Loop Detector (EMX-2630-1) is designed for advanced vehicle detection in access control systems requiring directional logic and dual loop monitoring. With a wide input range of 12VDC to 240VAC, this detector allows a single unit to be used across multiple installations, helping reduce inventory requirements.

This model features DETECT-ON-STOP™ (DOS) technology, enabling detection only when a vehicle comes to a complete stop. This function is especially useful in tight spaces where cross traffic could otherwise cause false activations. The compact housing and built-in diagnostics make it suitable for installations where space and performance visibility are critical.

Key Features

• Dual channel design with independent loop monitoring
