MS1

Type MS
Bare Metal Element Resistors
RIEDON
Designed For Current Sensing or Shunt Applications
Economical Bare Metal Resistance Element
Special Lead Configuration Available
Welded, Flameproof Construction
Values from 0.005 Ohms, Tolerance to ±1%
Low Inductance
Riedon's bare element resistors were developed for current sensing and shunt applications. The
resistance element is a special ribbon alloy, with the tinned copper or copper-clad steel leads welded
to the element. This rugged construction offers a low-cost and reliable alternative to encapsulated
designs.
Since this design is so flexible, we list typical specifications and encourage your custom
applications. Please contact us for an optimum design for your application.
