National Loop Co. 40' (6' X 14') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 20' Wide Driveways - X-NL20-14

Preformed and pave-ready, the National Loop Co. 40' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a 14 AWG inductive loop for direct burial under asphalt, concrete, or gravel. Connected to a loop detector, it reports every vehicle that crosses the sensing area, giving the gate operator the non-contact detection that fills one of the two UL 325 entrapment protection slots. 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. With the 14' side crossing the lane and about 3' of clearance per edge, and the 6' side capturing vehicles in the direction of travel, the layout fits ranch entrances, farm properties, and estate homes with dual swing gates.

Features:

• 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
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
