National Loop Co. 34' (5' X 12') Direct Burial Vehicle Detection Loop with 75' Lead-In for 17' Wide Driveways - X-NL17-14-75

Designed to be paved over, the National Loop Co. 34' Direct Burial Vehicle Detection Loop with 75' Lead-In is a preformed 14 AWG inductive loop for new-surface installations. Teamed with a loop detector, it gives the gate operator the presence detection UL 325 counts as one of its two means of entrapment protection, so the gate reverses or holds open while a vehicle sits in the path. 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 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
