Safety Vehicle Loops

Vehicle Loop Detectors

Vehicle loop detectors are the perfect safety device for protecting your vehicle from a moving gate. Photocells are still an excellent choice for protecting your car, but are often fitted in the wrong position for gates that work with lorries and other heavy goods vehicles. To protect the vehicles and gates, loop detectors are invaluable.  In this section we will look at the different loop detection devices available and discuss their merits.

VM202 Loop Probe


Cutting up driveways to add ground loops looks unsightly and in some cases can be impractical or dangerous. Our solution is the Loop Probe. This self contained unit can be buried at the side of the driveway with a 12ft detection range letting it pick up a vehicle moving near the gate, the probe then sends a pulsed output to activate the gate and let a vehicle drive through. On smaller sites a sensitivity adjustment control allows the loop probe to detect at shorter distances, preventing a false trigger.

    • Simple and quick to install
    • Sensitivity adjustment
    • Robust water tight PVC outer casing
    • Pulsed output

Ultra Loop Detector


Loop detectors have been around for years, so it is refreshing when a company makes an improvement to this basic piece of equipment. The Ultra 2 includes a digital display showing you exactly what your loop is doing and how a vehicle is interacting with it.

  • Digital display
  • Pulse and prescence relay options
  • Frequency modulation so multiple loops can be used on site
  • ASB signal boost for use with lorries
  • Two channel version now available

MVP-E-TEC Loop Detector


The MPV-E-TEC is an evolution of the MPV-D-TEC and
Ultra 2. This vehicle loop system can be powered by 12V
upto 230V. As with other loop systems in the range the
detector provides multiple functions most notably the digital
display showing how much the loop is affected by vehicles
moving above. Quick adjustments can be made to the
sensitivity of the MPV-E-TEC by turning the dial above to
match the sensitivity required.

  • Digital display
  • Pulse and prescence relay options
  • Frequency modulation so multiple loops can be used on site
  • 11 pin base for din rail mounting

Preformed Loop Cable

The lightweight preformed loop is a ready-to-use loop that works with all SEA vehicle loop detectors. It is constructed of stranded wire conductors with XLP thermoplastic elastomer insulation jacketing. The outer shell is a flexible nonmetallic, .026″ diameter.The preformed loop is suitable for saw cut, tar and concrete installations. Available in two different sizes , 4×8′ and 8×12′ with a 50 ft lead.

  • Built-in lightning protection
  • Rugged and flexible TPE tubing
  • Overall diameter of 0.26”
