National Loop Co. 32' (4' X 12') Direct Burial Vehicle Detection Loop with 75' Lead-In for 16' Wide Driveways - E-NL16-18-75

Contractors laying new asphalt, concrete, or gravel can set the National Loop Co. 32' Direct Burial Vehicle Detection Loop with 75' Lead-In directly on the sub-base and pave right over it. Connected to a loop detector, it reports every vehicle that crosses the sensing area, giving the gate operator the non-contact detection that fills one of the two UL 325 entrapment protection slots. 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 12' side spans the travel lane while the 4' side runs in the direction of traffic, leaving roughly 2' of clearance on each edge, an arrangement well suited to common 2-car suburban driveways and small apartment building lots.

Features:

• 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
• 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
