Indian Lab Suppliers supplies the Rheostat, Constantan (Eureka) Wire (Product ID: 10796) as part of its electrical and electronics range. It is a sliding rheostat wound with constantan (Eureka) wire, usable as a variable resistance or a potential divider.
Quick Answer
Layers of oxidised constantan wire are wound on an insulated, heat-resistant porcelain tube held between moulded bakelite or aluminium end supports. A heavy brass slider with a phosphor-bronze double contact runs along the guide rod. Three brass terminals are fitted: one to the slider and one to each end of the winding. Versions are made for current ratings from 0.6 A to 8 A; please confirm the resistance value you need at quotation.
Key Features
Works as a variable resistance (one end + slider) or potential divider (both ends + slider) · Porcelain former helps dissipate heat
