National Loop Co. 30' (4' X 11') Direct Burial Vehicle Detection Loop with 75' Lead-In for 15' Wide Driveways - E-NL15-18-75

Designed to be paved over, the National Loop Co. 30' Direct Burial Vehicle Detection Loop with 75' Lead-In is a preformed 18 AWG inductive loop for new-surface installations. Once a loop detector reads its signal, the loop covers the non-contact vehicle detection that UL 325 requires as one of the two means of entrapment protection for automated gates. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. Its 11' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to 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
