The BPR02K brings a high-precision Vishay wiper element to a solder-free 22mm panel potentiometer, with a clear 0-100% scale and secure mechanical stops at each end of travel so you always know exactly where the dial sits. At 2.2kΩ, it's built for smooth, stable manual speed reference on variable speed drives.
- Solder free for easy panel mounting
- High precision Vishay wiper
- Scale reads 0-100%
- Smooth and stable operation
- Secure stops at start/end of adjustment

Frequently Asked Questions
How do I wire it for increasing vs decreasing output?
The centre terminal is the wiper; which outer terminal you connect to your positive supply determines whether output increases or decreases as you turn the dial clockwise — simply swap the two outer connections to reverse the direction.
Is 2.2kΩ the right value for my inverter/VSD?
Check your inverter or drive manual for its speed-reference potentiometer specification — EMAS offers 1K, 2.2K, 5K, and 10K versions, and using the wrong value can give a non-linear or limited speed range. Match the kΩ value the drive manufacturer specifies.
What does the "Vishay wiper" spec mean in practice?
It refers to the precision contact element used inside the potentiometer, giving smoother, more consistent resistance change through the full 270° travel compared to lower-grade wipers — useful where fine, repeatable speed adjustment matters.
Is it suitable for washdown or outdoor panel mounting?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets.
Industry Applications
- Variable speed drive control — manual speed reference for VSDs on pumps, fans, and conveyors
- Machine control panels — operator-adjustable process parameters (speed, flow, dosing rate)
- Process equipment requiring fine adjustment — precision dosing, mixing speed, or flow control where the 0-100% scale aids repeatable settings
