MATERIAL SPECIFICATIONS

Element: copper-nickel alloy or nickel-chrome alloy,

depending on resistance value

Core: ceramic, steatite or alumina, depending on physical

size

Encapsulant: silicone molded construction

Housing: aluminum with hard anodic coating

End Caps: stainless steel

Standard Terminals: For RE77 and RE80 terminals are

threaded stainless steel. All others are 60/40 tin/lead (Sn/Pb)

w/nickel underplate on copper clad steel core terminal.

Part Marking: Dale, model, wattage, value, tolerance, date

code

NON-INDUCTIVE (TYPE N)

Models of equivalent physical and electrical specifications

are available with non-inductive (Ayrton-Perry) winding.

They are identified by substituting the letter N for G in the

model number (RE60N, for example).
