High-precision multiple section potentiometer for industrial use
Conductive plastic potentiometers for position sensing are commonly used for automotive engineering and many industrial applications. They are inexpensive and offer great precision. And with more than 50 to 100 million wiper movements, the life expectancy of higher-end versions is suitable for even intense mechanical requirements. But the potentiometer technology is continuously advancing, as evidenced, for example, by the new, highly durable Multiple Section Potentiometers. With multiple channels, they are especially well suited for applications requiring redundancy.
Through exclusive UK distributor Variohm EuroSensor, Novotechnik is now offering a multiple-section version of the proven precision potentiometer P2500, featuring up to six channels. This component is particularly well suited for applications where safety is a concern. The combination of plastic resistive track and multi-pronged precious metal wiper, a sturdy full-metal housing, and the durable 6mm stainless steel shaft provide for a long service life free of contact issues. This potentiometer is offered with rotation angles of 120, 240, or 345 degrees and allows continuous mechanical rotation.
In addidtion, it is very accurate, featuring a resolution degree of 0.01 and a linearity of +/-0.3 per cent, and the channels are calibrated to be well synchronised with each other. The fact that the shaft is running on multiple ball bearings allows for high bearing loads; ambient temperatures of -40 to 100degC are acceptable. The maximum operating speed is 2000rpm. These features make the new multiple section potentiometers the practical solution for a broad spectrum of different applications, such as steering systems for maritime vessels, weighing systems, or controls for special engineering.
