National Loop Co. 30' (4' X 11') Direct Burial Vehicle Detection Loop with 50' Lead-In for 15' Wide Driveways - E-NL15-18-50

Preformed and pave-ready, the National Loop Co. 30' Direct Burial Vehicle Detection Loop with 50' Lead-In is an 18 AWG inductive loop for direct burial under asphalt, concrete, or gravel. Working through a compatible loop detector, it detects the metal mass of vehicles above, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. Since the conduit protects the wire, the loop sits directly on the sub-base and gets buried under the new asphalt, concrete, or gravel surface. With the 11' side crossing the lane and about 2' of clearance per edge, and the 4' side capturing vehicles in the direction of travel, the layout fits standard 2-car driveways on modest suburban lots.

Features:

• More cost-effective than hand-wound loop installations
• Fills the non-contact detection role UL 325 assigns to vehicle loops in a 2-device entrapment protection system
• Designed for vehicle detection with gate operators, parking barrier gates, overhead doors, traffic signals, arming devices, and vehicle counters
• Wound from one continuous, non-spliced wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
• Predetermined number of turns removes the guesswork of achieving optimal read range
