GateCrafters Exit Vehicle Motion Detector - 50' Lead Wire (VMD202-50)

The Gate Crafters sensor is a multipurpose exit sensor and vehicle detector that allows hands free access; and, because of its simple design, it is compatible with most gate openers including the Estate Swing, Apollo, Zareba, and many others. The single piece design provides the installer with a simple installation procedure. The Gate Crafters Exit Sensor is buried in the ground so a potential intruder or vandals do not notice it. The Gate Crafters have a wide range of power supply options from 9V to 41V AC or DC. Low current consumption makes it an excellent choice for solar power applications.

The Gate Crafters sensor uses a passive probe sensor to detect changes in the earth's magnetic field. These changes are caused by a movement of ferrous metal objects such as a car in the proximity of the probe. The sensing area of each probe is in the shape of about 15-foot circle. The size of this detection circle changes with the size and speed of the moving car. The Gate Crafters sensor can be buried in the ground about 6 inches deep parallel to the paved driveway. It also can be placed 2 inches deep in asphalt or concrete under the path of the vehicle.

Note: Exit wands/sensors should not be used on properties in which the driveway gate is designed to keep in pets, children or livestock due to the possibility for unintentional openings. Our suggestion is to use a keypad for exiting so the gate will only open when it is intended to by code.

Use this formula to calculate how far from the gate the loops should be placed so that by the time a car reaches the gate, the gate will be completely open:

Exit Loop formula:    x*(y*1.46)=z

x = time for gate to open in seconds.
y = Desired MPH to reach gate.
z = how far from gate.

FYI - 1.46 converts miles per hour to feet per second. We also recommend adding in 10 to 20 feet so the gate is fully open at a comfortable distance from the gate.

For placement of a safety loop before and after the gate use the formula below. A safety loop is designed to stop the motion of the gate before the car reaches the gate. The distance below should give an ample amount of time for the gate to stop before hitting a vehicle:

Safety Formula:     4 feet before a closed gate and after an opened gate.

“We are always getting questions about how gate exit wands work and how they are different from exit loops.

Exit wands are what is know as a magnetometer which senses changes in the Earth’s magnetic field. An easy way to explain how exit wands work is to picture a boat traveling through the water. As the boat is traveling it is creating waves. As your car travels through the magnetic field of the Earth it creates similar waves, like the boat. The exit wand’s magnetometer picks up on these waves as you travel by the wand. One downside of exit wands is that they do lose sight of your vehicle when it is stopped.

Gate Crafters carries 5 different types of exit wands that work very similar to each other. The only difference between these wands is some of their features. The GTO/PRO wireless exit wand is wireless between the magnetometer and receiver. The Gate Crafters exit wand is manufactured by EMX and has been around for years. The GTO exit wand is recommended for use with other GTO openers and accessories. The Estate Swing exit wand does come with a range control board that allows you to adjust the sensitivity of the magnetometer. This feature allows you tune down the range of the exit wand so that vehicles such as a lawnmower don’t set open your gate, but this isn’t a complete failsafe, as it will still operate the gate opener when something is nearby. The Estate Swing Deluxe Exit wand is the most different from the other exit wands. It is constructed out of copper and features a ground cable that attaches to a grounding rod that helps protect this exit wand from lightning strikes. The other 4 exit wands do not have this feature and are susceptible to damage from lightning strikes. Also, the Estate Swing Deluxe Exit Wand comes with a 5 year warranty, which is longer than any other exit wand we sell.

Exit loops differ from exit wands in that they are buried in the driveway in a loop and are wire to the gate opener. The way exit loops work is that they detect the presence of metal (your car) above the loop. It does not matter if your car is moving or not, the loop will detect the car. Besides being used to exit your property, exit loops are used for safety. When exit loops are used as a safety device, they will prevent your gate from closing on your car, when they detect a car nearby to your gate. The exit loop is wired to an exit loop detector, which is then wired into your gate opener’s control board.
