National Loop Co. 26' (4' X 9') Direct Burial Vehicle Detection Loop with 20' Lead-In for 13' Wide Driveways - E-NL13-18-20

Placed before the paving crew arrives, the National Loop Co. 26' Direct Burial Vehicle Detection Loop with 20' Lead-In is an 18 AWG inductive loop that disappears under the finished surface. 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. The 9' 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 single-car driveways with a walkway beside them and rural homes with truck access.

Features:

• Liquid-tight conduit stands between the wire and sharp stones, chemicals, ground movement, and harsh weather
• Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
• 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
