National Loop Co. 50' (6' X 19') Direct Burial Vehicle Detection Loop with 250' Lead-In for 25' Wide Driveways - E-NL25-18-250

Preformed and pave-ready, the National Loop Co. 50' Direct Burial Vehicle Detection Loop with 250' Lead-In is an 18 AWG inductive loop for direct burial under asphalt, concrete, or gravel. Paired with a compatible loop detector, it senses the metal mass of a passing car or truck and signals the gate operator to open, hold, or reverse, providing one of the two means of entrapment protection UL 325 requires 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 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:

• 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
• 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
