Vishay-Sfernice 533, 534, and 535 Multi-Turn Wirewound Potentiometers
There's Nothing Passive About Sfernice
Vishay-Sfernice 533, 534, and 535 Series are low-cost, 7/8", multi-turn precision potentiometers that are ideal for applications in which precision and frequent adjustment of current or voltage is needed. Bushing and servo mount versions are available, featuring gold-plated terminals and stainless steel shafts. All 533, 534, and 535 Series potentiometers have a rotational life of one million cycles, standard tolerance of ±5%, and linearity of ±0.25% (down to 0.05% on request). Non-standard features are available, including multi-gangs, cables, harnesses, sealing, metric shafts, plastic shafts for high dielectric strength, high torque, center tap, and slipping clutch - contact your local Allied Sales office for details.
