National Loop Co. 34' (5' X 12') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 17' Wide Driveways - E-NL17-18

Designed to be paved over, the National Loop Co. 34' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a preformed 18 AWG inductive loop for new-surface installations. Working through a compatible loop detector, it detects the metal mass of vehicles above, satisfying the non-contact detection that UL 325 lists as one of its two required means of entrapment protection. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. The 12' side covers the travel lane with roughly 2' 6" of clearance on each side, and the 5' side reads vehicles as they roll through, making it a fit for 2-car drives in newer subdivisions and homes with boat or trailer parking.

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
