BD LOOPS RL 32-40 PREFORMED DIRECT BURIAL 4'X12' OR 6'X10' w/ 40' LEAD

The BD Loops RL 32-40 is a preformed direct burial inductance loop with a 32 ft perimeter (4 ft x 12 ft or 6 ft x 10 ft) and a 40 ft lead-in. The loop section is solid 16 AWG copper wire with PE insulation inside a doped PVC outer jacket, with 2 to 4 turns depending on loop and lead-in size. It goes under concrete, asphalt or pavers, or in gravel and dirt roads, for vehicle detection at gates and doors. The solid wire holds its shape, so in a concrete pour the loop stays on top of the rebar. The lead-in conductors are bound inside the jacket, so there is no twisting. A flex yoke with a 1/2 in coupler accepts PVC conduit for the lead-in run. There is no air pocket around the wire as with a loop pulled through PVC pipe, which cuts down on false detections from ground vibration. Each loop is tested 3 ways at the factory. The wire is rated for direct burial, 600 V and 167°F (75°C). What's Included One BD Loops RL 32-40 preformed direct burial loop, 32 ft perimeter, with 40 ft lead-in attached Cable ties Ground stakes Lead-in labels Before You Order Concrete: set the loop on top of the rebar or wire mesh, never below, offset from the pattern, and tie it down. Run the lead-in under the rebar. Pavers or asphalt: lay the loop in a 2 in wide, 3 to 4 in deep trench. Under asphalt, keep at least 1/8 in of sand between the loop and the hot asphalt. Gravel: bury it 7 to 10 in deep. BD Loops lists 14 in as the maximum depth. Choose the size by the area to cover (4 ft x 12 ft or 6 ft x 10 ft). The 40 ft lead-in must reach the loop detector without a splice. Run it in 1/2 in Schedule 40 or 80 rigid PVC with glued joints. A vehicle loop detector is required and is not included. Keep the loop 4 ft from the gate or door and 4 ft from other loops. Detection height is about 2/3 of the loop's short side. RL part numbers have a 40 ft lead-in and EL part numbers have a 60 or 100 ft lead-in. BD Loops lists RL for residential and EL for commercial installs. For saw-cut slots in existing pavement, use a BD Loops SC saw-cut loop instead.
