And with more than 50 to 100 million wiper movements, the life expectancy of higher-end versions is suitable for demanding mechanical applications. Now, highly durable multiple section potentiometers with multiple channels offer additional redundancy.

Now available in the UK from Variohm Eurosensor, Novotechnik's P2500, featuring up to six channnels, combines plastic resistive track and multi-pronged precious metal wiper, a sturdy full-metal housing and durable 6mm stainless steel shaft. The potentiometer is offered with rotation angles of 120, 240, or 345 degrees and allows continuous mechanical rotation.

The unit offers a resolution 0.01 of a degree and a linearity of +/-0.3 percent. Additionally, the channels are calibrated to be well synchronized with each other. The fact that the shaft is running on multiple ball bearings allows for high bearing loads; ambient temperatures of -40 to 100°C are acceptable. The maximum operating speed is 2,000 rpm.
