National Loop Co. 52' (6' X 20') Direct Burial Vehicle Detection Loop with Custom Length Lead-In for 26' Wide Driveways - K-NL26-14

Every new paving project gains reliable vehicle detection with the National Loop Co. 52' Direct Burial Vehicle Detection Loop with Custom Length Lead-In, a preformed 14 AWG inductive loop. 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. Because it ships encased in heavy-duty, liquid-tight conduit, the loop lays directly on the graded sub-base and is then paved over under fresh asphalt, concrete, or gravel. With the 20' side crossing the lane and about 3' of clearance per edge, and the 6' side capturing vehicles in the direction of travel, the layout fits 3-car-wide residential drives and light commercial entries.

Features:

• 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
• Works wherever vehicles need detecting: automatic gates, parking barriers, overhead doors, traffic signals, arming devices, and vehicle counters
• 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
