The BPR01K gives you solder-free 1kΩ speed control in a standard 22mm panel cutout, with the centre terminal wired as the wiper and outer terminals configurable for increasing or decreasing output as you turn the dial. It's a direct drop-in replacement for common branded parts like the XB5AD912R1K and M22-R1K, priced well below sourcing the genuine branded part and held in UK stock for fast dispatch, and pairs well with leading-brand inverters for manual VSD speed reference.
Technical Details
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 1kΩ the right value for my inverter/VSD?
Check your inverter or drive manual for its speed-reference potentiometer specification — EMAS offers 1K, 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 XB5AD912R1K or M22-R1K — this is a listed drop-in replacement for both, at a lower price and without the wait for a genuine spare.
Is it suitable for washdown or outdoor panel mounting?
Yes — IP65 rated, protected against dust ingress and low-pressure water jets.
