Malvern, Pa. Vishay Intertechnology, Inc. has introduced two new series of 9-mm multi-ganged potentiometers with an ultra-compact module, measuring 0.375 in. x 0.75 in. (9.52 x 11.35 mm). These new devices also offer designers greater flexibility with the availability of variable standard and custom models.
The new Vishay Sfernice P9S and P9A potentiometers can be used in audio, general industrial, aerospace, and professional applications such as mixing desks, cash dispensers, lighting controls, fusion pumps, and volume and speed controls for automotive and consumer audio/video systems.
The P9S is optimized for industrial and military applications with a CERMET resistive element, while the P9A features a conductive plastic resistive element for professional audio applications. Both types can be used in multiple-device assemblies with up to seven modules. An integrated center mechanical detent is optional. Custom designs are available.
The resistance values for the P9A and P9S are 1 KΩ to 1 MΩ and 47Ω to 2.2 MΩ (linear), and 2.2 KΩ to 500 KΩ and 100Ω to 1 MΩ (non-linear), respectively. Standard tolerance for both potentiometers is ±20% with values of ±5% and ±10% available for the P9S on request. The P9A features a temperature coefficient of ±1,000 ppm, and the P9S provides a temperature coefficient of ±150 ppm. Insulation resistance for both devices is 100 MΩ at 250 Vdc, and dielectric strength is 300 Vac over one minute.
Available shaft styles include 3.5-mm- and 6-mm-diameter options in round, slotted, flat, and knurled styles in lengths of 15 mm, 20 mm, 25 mm, and 30 mm. Specific shafts and designs are also available on request.
Pricing for U.S. delivery is $1.90 in quantities of 1,000. Samples of the P9 are available now, with lead times of ten weeks for production quantities.
