The BPR05K puts 5kΩ of precise, solder-free speed control into a standard 22mm cutout, using a Vishay wiper for smooth, repeatable adjustment across the full 270° travel. It's a listed drop-in replacement for the XB5AD912R4K7, so upgrading a worn or discontinued branded potentiometer is a straightforward swap.
- 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 5kΩ 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.
Is this a direct replacement for my existing branded potentiometer?
Likely yes if your existing part is an XB5AD912R4K7 — this is a listed drop-in replacement for that part number.
Is it suitable for washdown or outdoor panel mounting?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets.
