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

Designed to sense vehicles without any surface teardown, the National Loop Co. 42' Saw Cut Vehicle Detection Loop with Custom Length Lead-In is a preformed 18 AWG loop that drops 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. Installers saw a 1/8" by 1" deep slot into the existing surface, drop the prewound loop in, and seal the slot against moisture. With the 15' 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 2-car plus guest parking and wider rural/farm gate entrances.

Features:

• Factory-set turn count means optimal read range without any on-site adjustment
• Precisely stacked wires let loop sealant fully encapsulate the loop for lasting weather protection
• 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
