Product Code : SCL-EAE-14629
Indian Lab Suppliers supplies the Sliding Rheostat Dual Tube (Product ID: 14629) as part of its electrical and electronics range. It is a linear sliding rheostat with two wound tubes, giving a wider resistance range and higher current than a single tube.
Quick Answer
Constantan or nichrome wire is wound on two insulated tubes (porcelain, bakelite or composite), and a metal rider slides along them to vary the resistance. Models range from 5 Ω to 500 Ω and 2 A to 10 A, with lengths of 30–100 cm; higher-resistance models carry less current. Brass or nickel-plated terminals are fitted on a metal or wooden base. Please confirm the resistance and current rating together at quotation.
