National Loop Co. 22' (4' X 7') Direct Burial Vehicle Detection Loop with 75' Lead-In for 11' Wide Driveways - X-NL11-14-75

The National Loop Co. 22' Direct Burial Vehicle Detection Loop with 75' Lead-In is a 14 AWG inductive loop that arrives preformed and ready to install, with its lead-in attached as part of the same continuous wire. 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. The 7' 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 slightly wider suburban single-car drives and older neighborhoods with wider lot cuts.

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
