BD Loops Prefabricated Saw-Cut Loop - Various Sizes

Reliable and Durable Vehicle Detection for Concrete and Asphalt Installations

BD Loops Preformed 3/16” Saw-Cut Inductance Loops are the industry’s leading solution for vehicle detection in gate systems, designed for fast, reliable installation in existing concrete or asphalt surfaces. Engineered with durability and precision in mind, BD Loops offer a complete loop system that delivers long-lasting performance and requires minimal maintenance, making it the go-to choice for professional installers.

Whether you’re working on a commercial gate operator or a residential swing gate, BD Loops make vehicle detection seamless, reliable, and efficient.

Key Features

• Extra Layer of Protection: Every loop is made with a durable outer jacket that tightly binds and protects the 16 AWG copper wire. This ensures the loop and lead-in wires stay secure and free from damage during and after installation.
• Integrated Backer-Rod: For installations using a 3/16” saw-cut groove, there’s no need to use a separate backer rod. The backer rod is already built into the loop’s wire, making installation simpler and quicker.
• Pre-Tested Quality: BD Loops ensures every loop is tested in three ways before leaving the factory. This guarantees you receive a product that will perform reliably and without issues.
• Efficient Sealant Use: The loop’s design minimizes the amount of loop sealant needed - up to 40% less compared to a ¼” wide groove. The loop fills a larger portion of the groove, ensuring a smoother, more even seal.
• Fit Guarantee: BD Loops can be adjusted up to 4 feet smaller on-site. With a slight adjustment to the dog-ear corners or by pushing excess loop into the lead-in run, you’re guaranteed a perfect fit every time - even if your cut isn’t exact.
• Saves Time and Money: BD Loops are designed to save time on every job. Using the BD-LS Gray color or BD-LS Black color sealant with a flat 3/16” tip allows you to seal the loop in one smooth pass, eliminating the need for multiple layers or waiting for sealant to settle.

What Makes BD Loops Stand Out?

The BD Loops Preformed Saw-Cut Loop is not just another inductance loop—it’s a game changer for professionals who prioritize efficiency, accuracy, and durability in their installations. BD Loops are crafted from solid 16 AWG copper wire, built to handle the wear and tear of everyday use, and offer a level of protection and ease of installation that far surpasses competitors.

With a design that allows for minimal waste of sealant and no need for twisting wires, BD Loops are engineered to make your job faster and simpler, all while ensuring that the loop stays protected for years to come.

Technical Specifications

• Wire Gauge: 16 AWG solid copper wire.
• Outer Jacket Material: Polyethylene (PE) with a durable outer protective coating.
• Insulation: PE/Nylon combination for maximum durability and performance.
• Number of Turns: 2-4 turns, depending on the loop and lead-in size.
• Voltage Rating: 600V.
• Temperature Rating: Up to 75°C (167°F).
• Loop Width: Designed for 3/16” wide saw-cut grooves.
• Rated for Direct Burial Use: Suitable for saw-cut applications, but can also be used in direct burial if necessary, although the direct burial version offers higher crush resistance.

Applications & Performance

• Slide Gates: Requires a minimum of two loops for accurate vehicle detection, with an optional third loop for exiting vehicles.
• Swing Gates: Minimum of three loops required for detection, with an optional fourth for exiting vehicles.
• Parking Garages & Driveways: Shallow groove depth (down to ¾” for indoor applications) makes BD Loops perfect for use in parking structures and residential driveways.

How It Works:

The loops operate on the principle of inductance, detecting metal objects like vehicles when they pass over the loop. The loop creates a magnetic field, and a loop detector monitors changes in this field to detect when a vehicle is present. The loop is most effective when installed at a depth of 1 ¼” to 1 ½” and in a groove at least 3/16” wide to prevent air pockets.

Installation Process:

1. Saw-Cut Groove: For optimal performance, cut the groove 1 ¼” to 1 ½” deep using a 3/16” blade. This ensures the groove is wide enough to prevent air pockets, allowing the sealant to fully encapsulate the loop wire.
2. Fit Guarantee: If the saw-cut pattern is slightly too large, adjust by trimming the dog-ear corner to reduce the loop size. If it’s too small, push the yoke down the lead-in run, making the loop smaller by laying the wires side by side.
3. Seal the Loop: Once the loop is in place, use BD-LS loop sealant to fill the groove in one smooth pass. For best results, make sure the surface is dry and clean before applying the sealant.

FAQs:

1. Do I need a loop detector with BD Loops?
   Yes, a loop detector is required for proper operation. BD Loops are compatible with all major loop detectors.
2. Can I modify the lead-in length?
   Yes, you can cut excess lead-in, but avoid cutting it too short to prevent weak spots in the circuit. It’s better to have more lead-in than too little.
3. Can BD Loops be installed near electrical lines?
   Yes, BD Loops are designed to resist interference from electrical lines and won’t trigger false detections in most cases.
