National Loop Co. 42' (6' X 15') Saw Cut Vehicle Detection Loop with 75' Lead-In for 21' Wide Driveways - X-NL21-18-75

A preformed 18 AWG inductive loop built for saw-cut installation, the National Loop Co. 42' Saw Cut Vehicle Detection Loop with 75' Lead-In detects vehicles passing over the driveway. 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. Fitting takes one shallow saw cut: a 3/16" slot, 1" deep, cleaned out, filled with the loop, and sealed with loop sealant. Its 15' 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 2-car plus guest parking and wider rural/farm gate entrances.

Features:

• Cuts down on faulty detection calls and repeat service trips thanks to consistent machine winding
• 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 length of Polypropylene-insulated wire, leaving no splice point between the loop and lead-in to fail
• 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
