National Loop Co. 38' (6' X 13') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 19' Wide Driveways - X-NL19-14

For driveways getting a fresh surface, the National Loop Co. 38' Direct Burial Vehicle Detection Loop with Custom Length Lead-In provides vehicle detection without cutting into the finished pavement. 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. Since the conduit protects the wire, the loop sits directly on the sub-base and gets buried under the new asphalt, concrete, or gravel surface. Its 13' side spans the travel lane while the 6' side runs in the direction of traffic, leaving roughly 3' of clearance on each edge, an arrangement well suited to 2-car drives with extra walkway room and estate-style rural homes.

Features:

• 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
• Saves labor cost compared with winding a loop by hand in the field
