National Loop Co. 68' (6' X 28') Saw Cut Vehicle Detection Loop with 20' Lead-In for 34' Wide Driveways - P-NL34-18-20

Built for retrofitting an existing paved driveway, the National Loop Co. 68' Saw Cut Vehicle Detection Loop with 20' Lead-In is a factory-wound 18 AWG inductive loop ready to lay into a saw-cut slot. 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. The install method is a 1/8" wide, 1" deep saw cut in the existing asphalt or concrete, with the loop laid in and sealed to finish the job. Its 28' side spans the travel lane while the 6' side runs in the direction of traffic, leaving roughly 3' of clearance on each edge, an arrangement well suited to 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
