GTO/Linear Pro FM139 Automatic Exit Sensor

   Quick Content Anchors
    DescriptionTop of Page

Automatically activates gate operators hands-free when a vehicle approaches. Designed for residential, agricultural, and commercial applications. Easy to install and requires only one-third the time of traditional exit and entry loop detector systems.

The exit wand is an electromagnetic sensor that detects moving metal masses within a 12-foot radius, allowing hands-free exit from automatic gate operators.

The Mighty Mule/GTO Exit Wand offers very low power consumption and a wide input voltage range, making it ideal for battery-powered applications. It is engineered to reject 50 Hz or 60 Hz line noise, improving detection reliability near power lines.

Note: Exit wands and sensors should not be used on properties where driveway gates are intended to contain pets, children, or livestock, as unintentional openings may occur. For these situations, we recommend using a keypad for exiting so the gate only opens when activated by a code.


Loop Placement Formula

Use this formula to calculate how far from the gate the loops should be place 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 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.

    Words from Senior Application Engineer Anthony GeatoTop of Page

Anthony Gaeto Application Engineer “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 loose 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 are 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 recommend for use with other GTO openers and accessories. The Estate Swing exit wand does come with a range control board that allow 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 lawn mower doesn'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 attach 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 a safety device, they will prevent your gate from closing on your car, when it detect a car nearby to your gate. The exit loop is wired to a exit loop detector, which is then wired into your gate opener’s control board.
