Commercial quality rotary potentiometers are divided into two nominal sizes (16mm and 20mm) and three product groups – the ECO all plastic potentiometer and the P16 and P20 metal case potentiometers.
Common features of the three product groups include:
- Conductive polymer (plastic) track giving a life of 20,000 cycles (or over twice the life of carbon tracks)
- Standard resistance range (E3 series: 1K0, 2K2, 4K7, 10K, 22K, 47K, 100K, 220K, 470K, 1M0 ohms)
- Note: Other resistance values are special and are priced on application
- Temperature Range: -10°C to +70°C
