National Loop Co. 20' (4' X 6') Direct Burial Vehicle Detection Loop with 250' Lead-In for 10' Wide Driveways - E-NL10-18-250

The National Loop Co. 20' Direct Burial Vehicle Detection Loop with 250' Lead-In is an 18 AWG inductive loop that arrives preformed and ready to install, with its lead-in attached as part of the same continuous wire. 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. Installation is a lay-and-pave job: set the loop on the graded sub-base, run the lead-in to the detector, and let the paving crew cover it. The 6' side covers the travel lane with roughly 2' of clearance on each side, and the 4' side reads vehicles as they roll through, making it a fit for standard single-car suburban homes, duplex driveways, and small farm entrances.

Features:

• One continuous, non-spliced wire runs through the loop turns and lead-in, eliminating splice failures
• Liquid-tight conduit stands between the wire and sharp stones, chemicals, ground movement, and harsh weather
• Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
• Factory-set turn count means optimal read range without any on-site adjustment
• 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
