Vishay / Sfernice produces fixed and variable resistors in most of the existing technologies. With its wide range and its capability to manufacture standard as well as custom designed products, Vishay / Sfernice covers applications in all market sectors. Included in their product line are encoders, potentiometers, power resistors, resistor networks and arrays, SMD, and thin film resistors.
Potentiometers are variable resistors that are commonly used for all applications involving a reasonable number of cycles (few tens of thousands, manually actuated). Mounted behind the front panel for various equipment, they frequently feature buttons mounted on their shafts. Typical applications include: setting the light or the brightness of a screen, turning the volume for an audio application, setting the speed on tool machining equipment, or various parameters for industrial remote controls.
Typical markets include:
Off-road tractors, excavators, cranes
Avionic : overrhead panels
Medical : syringe pumps
Industrial : various parameters to be set up on machines.
Key parameters defining a panel potentiometer:
Resistive element material: depending on the application could be cermet of conductive plastic
Overall dimensions, dependent on the available space for the application
Sealing level: dependent on customers' constraints
Lifespan requested directly related to the application
Variation laws: a few are available (please refer to datasheets)
Admissible power: wide-range function of the potentiometer model
Other common options: detents (torque increase in determined position) / switches: rotary or push-push / mutiple resistive modules (multi-gang potentiometers) / custom shafts and bushings/ inner and outer shafts actuating different resistive modules
In summary Vishay offers a very versatile family of products with a wide range of potential options.
Vishay's discrete resistors serve applications in virtually all major market sectors. Resistive technology options include thin film, thick film, metal oxide film, carbon film and wirewound, as well as Power Metal Strip?. Vishay is the number one manufacturer worldwide of wirewound and other power resistors, leaded film resistors, and thick film surface-mount resistors.
Rheostats offer the advantages of their variable resistors with higher available power ratings. Vishay rheostats can be used in a range of applications, including rugged, demanding ones.
