BD Loops SC 16-50 3x5 or 4x4 Preformed Saw-Cut Inductance Loop, 50' Lead-In
The BD-SC1650 is a preformed 3/16” saw-cut inductance loop for reliable vehicle detection in gate and door applications, featuring a 3×5 ft or 4×4 ft size with a 50 ft lead-in for easy installation.
BD-SC1650 3×5 or 4×4 Saw-Cut Loop with 50 ft Lead
The BD-SC1650 from BD Loops is a preformed 3/16” saw-cut inductance loop designed for reliable vehicle detection in gate, door, and traffic-control applications. This loop measures 3×5 ft or 4×4 ft and comes with a 50 ft lead-in for flexible installation distance to the detector.
Engineered for professional installers, BD Loops’ saw-cut loops are made with 16 AWG copper wire and backed by a durable polyethylene outer jacket that resists moisture and abrasion. The lead-in wires are tightly bound in a protective outer jacket, eliminating the need for twisting, and a built-in backer rod lets the loop and lead-in sit cleanly in a 3/16” saw-cut groove.
Key Features
- Preformed saw-cut loop—no on-site wire forming required
- Fits 3×5 ft or 4×4 ft layouts for standard vehicle detection zones
- Includes 50 ft lead-in for easy connection to the detector
- Durable outer jacket protects both the loop and lead-in from abrasion and water intrusion
- Lead-in tightly bound in a protective jacket—eliminates the need for twisting
- Built-in backer rod—no separate backer-rod needed in a 3/16” saw-cut groove
- Ready-to-install design saves time and ensures consistent loop geometry
Applications
The BD-SC1650 is ideal for automatic gate operators, barrier arms, parking controls, and industrial doors that use vehicle detection loops. Its saw-cut design makes it ideal for installations where a 3/16” or wider slot is cut into concrete or asphalt and sealed with loop sealant. For concrete pours or buried applications, use a BD Loops Preformed Direct Burial Loop instead.
