GTO / Mighty Mule PC Board w/tuning pot for Vehicle Sensor Exit Wand
The REWPOTPCB-01 is the internal replacement PC board with a tuning potentiometer used in selected GTO, Linear PRO and Mighty Mule vehicle sensor exit wands. The exit wand is buried beside the driveway and detects moving metal objects, such as cars or trucks, as they pass through the sensing area. The board processes that signal and provides the tuning adjustment used to fine-tune sensitivity.
This part is most often used to repair an existing exit wand instead of replacing the entire wand assembly. It can be helpful when the wand housing and cable are still usable but the internal electronics have failed, become unstable, or no longer respond correctly to tuning. Common symptoms include no vehicle detection, short detection range, false openings, or sensitivity that cannot be adjusted.
Compatibility depends heavily on wand model and production generation. Older adjustable wand assemblies may use this board, while some newer exit wands may be built differently or may no longer include the same range adjustment board. Always compare the original board, connector, housing and wand model before ordering.
Compatible With
The REWPOTPCB-01 is commonly associated with these vehicle sensor exit wand applications:
- GTO / Linear PRO vehicle sensor exit wands using an internal tuning potentiometer board
- Mighty Mule FM138 automatic gate opening sensor applications where the original board matches
- GTO / Linear PRO FM139 50 foot automatic exit sensor applications where the original board matches
- GTO / Linear PRO FM140 100 foot automatic exit sensor applications where the original board matches
- FM141 related vehicle sensor exit wand applications where the original board matches
- Select older adjustable exit wand assemblies; verify newer wand generations before ordering

Technician Note
False trips can come from board problems, but they can also be caused by poor wand placement, moving metal nearby, bad splices, water intrusion or sensitivity set too high.
Before Ordering Checklist
- Confirm the exit wand model is FM138, FM139, FM140, FM141 or another supported adjustable wand.
- Open the wand housing and compare the original board and tuning pot layout.
- Inspect the cable, splices and housing for water damage before replacing the board.
- Verify the board is the problem, not wand placement or external interference.
- Do not use this board on newer wand designs that do not match the original adjustable board.
Important Ordering Warnings
Some current replacement exit wands may not include or use the older range adjustment board. Verify the original internal board before ordering REWPOTPCB-01.
Professional Advisory
Vehicle sensors affect automatic gate movement. After repair, test the gate through several normal vehicle approaches and confirm all required safety devices remain working.
Product Questions & Answers
What does the REWPOTPCB-01 board control?
It controls the detection and tuning functions inside select GTO, Linear PRO and Mighty Mule vehicle sensor exit wands.
Which exit wand models are commonly associated with this board?
It is commonly listed with FM138, FM139, FM140 and FM141 style vehicle sensor exit wand applications, depending on wand generation and board style.
Will this fix an exit wand that false-opens the gate?
It may if the original board is unstable or damaged, but false openings can also be caused by placement, moving metal nearby, water intrusion, bad wiring or sensitivity set too high.
Do all new exit wands use this tuning board?
No. Some newer wand designs may not use the same adjustable range board. Compare the original board before ordering.
Can I replace only the board instead of the entire wand?
Yes, when the wand housing, cable and sensor assembly are still good and the internal board matches REWPOTPCB-01.
