Linear Pro Access REWPOTPCB-01 PC Board With Tuning Pot for Exit Wands
The REWPOTPCB-01 is the small service board used inside select Linear / GTO / Mighty Mule wired exit wand systems. The tuning potentiometer on the board allows the installer to adjust detection sensitivity so the sensor responds to vehicles in the intended area without constantly false-triggering. This part is normally ordered when the buried wand and cable are still usable but the electronics board has failed, been damaged by moisture, or can no longer be adjusted correctly. It should be matched to the exact wand family rather than treated as a universal vehicle detector board. If the exit wand has cable damage, a failed sensor coil, water-filled enclosure, bad power, or a control board input problem, replacing only this PC board may not solve the issue. Always troubleshoot the full low-voltage circuit before assuming the wand board is the only failed part.

Technician Note
If the wand cable has been cut, crushed, waterlogged, or hit by lightning, the board may not be the only failed component. Check the sensor, cable, power, and control input before replacing parts.
Before Ordering
- Confirm the existing board has the tuning potentiometer style.
- Match the board to the FM139, FM140, FM138, or FM141-style wand assembly.
- Inspect the enclosure for water damage or corrosion.
- Check voltage and relay output before ordering.
- Do not order this part if you need the complete wand cable/sensor assembly.
Professional Advisory
Low-voltage accessory boards are simple parts, but troubleshooting should be done safely. A qualified gate technician should handle repeated false openings, lightning damage, or wiring problems inside the operator cabinet.
Product Questions and Answers
Is REWPOTPCB-01 a complete exit wand?
No. It is the replacement PC board with tuning potentiometer for select wired exit wand assemblies.
Which exit wands is it commonly associated with?
It is commonly associated with FM139, FM140, FM138, FM141, and related GTO / Linear / Mighty Mule wired exit wand assemblies.
Will this fix a cut or damaged buried cable?
No. If the buried cable or sensor coil is damaged, the board alone may not repair the wand.
What does the tuning pot do?
The tuning potentiometer adjusts sensor sensitivity so the wand can respond to vehicles without excessive false triggers.
Can this board be used on the R4500 wireless exit wand?
Do not assume that. R4500 is a wireless exit sensor system and should be serviced with parts intended for that specific wireless setup.
