Kupu Whakataki
The Mighty Mule 50 ft. Driveway Vehicle Sensor (model FM138) is designed to automatically open your gate when a vehicle drives past its magnetic field. This allows for hands-free exit from your property without the need for a remote control or keypad. It is compatible with Mighty Mule and GTO Access Systems gate openers and is suitable for both residential and agricultural applications.
This wired sensor detects metal mass in motion and features a 12 ft. magnetic sensing range. The unit comes with a 50-foot cable for installation.

Tatūnga me te Tāuta
Proper installation of the FM138 vehicle sensor is crucial for optimal performance. The sensor is designed for direct burial and should be placed parallel to your driveway.
- Turanga: Position the sensor between 3 to 50 feet away from the gate. For optimal gate opening time, consider the length of your driveway and typical vehicle speed. A longer distance allows the gate more time to open before the vehicle reaches it.
- Te tarai: Dig a trench along the driveway where the sensor will be placed. The sensor should be buried no more than 12 inches deep. It is recommended to use conduit for the cable to protect it from environmental factors and potential damage.
- Takotoranga Pūoko: Ensure the sensor is laid flat and parallel to the driveway within the trench.
- Waea waea: Connect the sensor's cable directly to the appropriate terminals in your Mighty Mule Automatic Gate Opener control box. Refer to your specific gate opener's manual for detailed wiring diagrams. Ensure all connections are secure and waterproof.
- Whakamātautau: After installation, test the sensor by driving a vehicle past its magnetic field to confirm the gate opens automatically.

Nga Tohutohu Whakahaere
The FM138 vehicle sensor operates by detecting changes in its magnetic field caused by the presence of a large metal object, such as a vehicle. When a vehicle enters the 12-foot magnetic field, the sensor sends a signal to the gate opener control box, initiating the gate opening sequence.
- The sensor is designed for exit-only functionality, allowing vehicles to leave the property automatically.
- It works with both single and dual gate systems.
- No remote control or keypad input is required for exiting once the sensor detects a vehicle.
Te tiaki
The Mighty Mule FM138 sensor is designed for durability and minimal maintenance. However, periodic checks can ensure its longevity and reliable operation:
- Tirohanga taura: Periodically inspect the exposed portions of the cable for any signs of wear, damage, or rodent activity. Repair or replace damaged sections promptly.
- Te Whakakore i ngā Para: Ensure the area directly above and around the buried sensor is clear of excessive debris, heavy foliage, or large metal objects that could interfere with its magnetic field detection.
- Taki Hononga: Annually, check the wiring connections at the control box to ensure they remain tight and free from corrosion.
Raparongoā
If your Mighty Mule FM138 sensor is not functioning as expected, consider the following:
- Gate Not Opening:
- Verify all wiring connections to the control box are correct and secure.
- Ensure the sensor is buried at the correct depth (no more than 12 inches) and is not obstructed by large non-metallic objects.
- Confirm the gate opener itself is powered and functioning correctly.
- False Triggers (Gate Opens Without Vehicle):
- Check for any large metal objects (e.g., metal lawn ornaments, buried pipes) near the sensor's detection zone.
- Ensure the sensor is not too close to the gate opener's motor or other electrical components that might cause interference.
- Some gate opener models may have sensitivity adjustments in the control box; consult your gate opener manual.
- Mahi Mokowhiti:
- Inspect the cable for any damage or breaks, especially if it was not installed in conduit.
- Check for loose connections at the sensor or control box.
For persistent issues, contact Mighty Mule customer support or a qualified gate technician.
