Long Life 50 Degree Potentiometer

You told us that you wanted a 50 degree potentiometer for the RBT that lasted longer than the standard one. We built ourselves a test rig and ran a load of the old design through a range of life tests to get some solid data that we could discuss with the manufacturer. To cut a long story short, the manufacturer has created a new potentiometer design with an improved track layout. We have had these running on the test rig for many 000s of operations now, and the ones we have stripped down show negligible signs of wear. Our tests to establish an exact figure will take some time to conclude but early results are very encouraging, and we are pleased to say that these are now available.
