National Loop Co. 68' (6' X 28') Saw Cut Vehicle Detection Loop with 175' Lead-In for 34' Wide Driveways - X-NL34-18-175

Made for gate and access-control upgrades, the National Loop Co. 68' Saw Cut Vehicle Detection Loop with 175' Lead-In is an 18 AWG inductive loop, machine-wound and ready to seal into existing pavement. 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. Installation calls for sawing a 3/16" slot 1" deep into existing asphalt or concrete, laying the loop in the slot, and sealing it, with no hand-winding or turn counting required. With the 28' 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 industrial or municipal lots and large estate entrances.

Features:

• Predetermined number of machine-wound turns removes the guesswork of achieving optimal read range
• Neatly stacked turns accept loop sealant completely, locking out moisture for long service life
• Optimizes read range, eliminates faulty signals, and minimizes callbacks
• Saves labor cost compared with winding a loop by hand in the field
• Provides the non-contact vehicle detection UL 325 gate systems count toward their two required means of entrapment protection
• Works wherever vehicles need detecting: automatic gates, parking barriers, overhead doors, traffic signals, arming devices, and vehicle counters
• One continuous, non-spliced Polypropylene-insulated wire runs through the loop turns and lead-in, eliminating splice failures
