MRPR-3 Series - 19.7mm High Power Reed Switch

DataSheet:Littelfuse Reed Switches MRPR-3 datasheet

A miniature, normally open switch with a 19.69mm long x 2.84mm diameter (0.770" x .112") glass envelope. Capable of switching up to 200Vdc at 50W. It is rated to carry 3A and switch 1.5A. Available sensitivity range of 22-43 AT. High insulation resistance of 1010 ohms minimum and contact resistance of less than 100 milliohms. Ideally suited for limit sensing, telecom, office equipment and automotive applications. Will handle light inductive loads with no suppression circuitry.

Features:

  • Normally open switch capable of switching 200Vdc or 1.5A at up to 50 Watts
  • Available sensitivity range of 22-43 AT

Benefits:

  • Hermetically sealed switch contacts are not affected by and have no effect on their external environment
  • Zero operating power required for contact closure

Applications:

  • Limit switching
  • Telecom
  • Office equipment
  • Light inductive loads
