National Loop Co. 80' (6' X 34') Direct Burial Vehicle Detection Loop with 250' Lead-In for 40' Wide Driveways - E-NL40-18-250

Sized to match a specific driveway width, the National Loop Co. 80' Direct Burial Vehicle Detection Loop with 250' Lead-In is a factory-wound 18 AWG loop for pave-over vehicle detection. Paired with a compatible loop detector, it senses the metal mass of a passing car or truck and signals the gate operator to open, hold, or reverse, providing one of the two means of entrapment protection UL 325 requires for automated gates. 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. Its 34' side spans the travel lane while the 6' side runs in the direction of traffic, leaving roughly 3' of clearance on each edge, an arrangement well suited to distribution centers, heavy equipment dealerships, and semi-truck yards.

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
