National Loop Co. 20' (4' X 6') Saw Cut Vehicle Detection Loop with 100' Lead-In for 10' Wide Driveways - P-NL10-18-100

Gate installers can turn an existing driveway into part of the safety system with the National Loop Co. 20' Saw Cut Vehicle Detection Loop with 100' Lead-In, a preformed 18 AWG inductive loop. Once a loop detector reads its signal, the loop covers the non-contact vehicle detection that UL 325 requires as one of the two means of entrapment protection for automated gates. Fitting takes one shallow saw cut: a 1/8" slot, 1" deep, cleaned out, filled with the loop, and sealed with loop sealant. Its 6' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to standard single-car suburban homes, duplex driveways, and small farm entrances.

Features:

• One continuous, non-spliced Polypropylene-insulated wire runs through the loop turns and lead-in, eliminating splice failures
• 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
