The MagnaSensor VD964 is a magnetic ground sensor for detecting vehicles, which can be used either as a pulse to activate the gate or barrier in free exit applications, or as a prescence sensor for safety applications.
 
No loops need to be cut or laid, the sensor does the work of the loops. Simply drill a 20mm hole in the road for the sensor and cut a channel for the pre-wired cable directly back to the controller. Back fill the channel and connect the wires. The sensor can also be installed horizontally in 30mm conduit.
 
Unlike ordinary loop detectors, the sensor adjusts for most drainage and access covers. With no loops to fit there is less mess, and installation takes a fraction of the time
