Rotary rheostats provide a full scale variation in less than one turn, for power ratings from 16 to 300 watts.
Higher power ratings are achieved by assembling several units.
Each rheostat is built at the required ohmic value, in the range of feasible values.
These products, which we provided for decades, have proven their quality and durability time and again.


  • the windings are made of low-temperature coefficient resistance wire to insure the best stability of the ohmic value

  • the slider mechanisms are optimized to provide a smooth motion and a high resistance to wear (durability)

  • numerous options are available: type of terminal connections, housing, manual or motorized slider drive, etc.
