BD Loops RL 52-40 6x20 Preformed Direct Burial Inductance Loop, 40' Lead-In

BD Loops RL 52-40 is a preformed direct burial inductance loop engineered for reliable vehicle detection in underground installations. The loop has a 52’ perimeter and fits a 6x20 loop pattern, with a 40 ft lead-in for routing back to the loop detector. The rigid loop section is constructed using solid 16 AWG copper wire, helping it stay properly positioned during installation. A durable outer jacket tightly binds and protects the conductors for long-term reliability. This design reduces air gaps that can contribute to phantom detections caused by vibration. Each loop is tested multiple ways before leaving the factory to ensure dependable performance.
