Advanced Magnetic Loop for Vehicle Detection in 13.12 ft (4 m) Car Barriers

The SYSLM4 magnetic loop, together with metal mass detector model FJCD621, is a security device that prevents the barrier arm from going down if a vehicle is beneath it. It also sends the order to close the barrier once the vehicle has passed.

Note: The SYSLM6, SYSLM4 loops, and the FJCD621 detector are designed for applications with standard vehicles and vans. For applications with trailers, trucks, and similar, please contact our  Engineering Department.
