National Loop Co. 50' (6' X 19') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 25' Wide Driveways - E-NL25-18

Built for sites where saw-cutting is not an option, the National Loop Co. 50' Direct Burial Vehicle Detection Loop with Custom Length Lead-In is a preformed 18 AWG loop encased in liquid-tight conduit. 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. 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 19' side covers the travel lane with roughly 3' of clearance on each side, and the 6' side reads vehicles as they roll through, making it a fit for estate properties, horse farms, and private road entrances.

Features:

• 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 wire, leaving no splice point between the loop and lead-in to fail
• Heavy-duty, liquid-tight conduit shields the loop from sharp stones, chemicals, ground heaving, and harsh weather
• Fully assembled at the factory, so there is nothing to wind, count, or connect before paving
• Predetermined number of turns removes the guesswork of achieving optimal read range
• Saves labor cost compared with winding a loop by hand in the field
• Provides the non-contact vehicle detection UL 325 gate systems count toward their two required means of entrapment protection
