National Loop Co. 40' (6' X 14') Direct Burial Vehicle Detection Loop with 175' Lead-In for 20' Wide Driveways - X-NL20-14-175

Placed before the paving crew arrives, the National Loop Co. 40' Direct Burial Vehicle Detection Loop with 175' Lead-In is a 14 AWG inductive loop that disappears under the finished surface. Wired to compatible automated system, the loop counts as one of the two means of entrapment protection UL 325 requires for gate operators, detecting the metal of any vehicle over the sensing area so the gate stops or reverses before contact. 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 14' 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 ranch entrances, farm properties, and estate homes with dual swing gates.

Features:

• 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
• Arrives fully assembled and ready to install under new asphalt, concrete, or gravel
• 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
