National Loop Co. 20' (4' X 6') Direct Burial Vehicle Detection Loop with 30' Lead-In for 10' Wide Driveways - K-NL10-14-30

Every new paving project gains reliable vehicle detection with the National Loop Co. 20' Direct Burial Vehicle Detection Loop with 30' Lead-In, a preformed 14 AWG inductive loop. 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. The 6' side covers the travel lane with roughly 2' of clearance on each side, and the 4' side reads vehicles as they roll through, making it a fit for standard single-car suburban homes, duplex driveways, and small farm entrances.

Features:

• Factory-set turn count means optimal read range without any on-site adjustment
• 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
