DRR-129 Series - 50.8mm High Voltage Reed Switch

DataSheet:Littelfuse Reed Switches DRR-129 datasheet

A standard, normally open switch with a 50.80mm long x 5.25mm diameter (2.000" x .207") glass envelope, capable of high voltage and power switching up to 400Vdc at 100W. It is rated to carry 6A and switch 3A. Available sensitivity range of 42-83 AT. High insulation resistance of 10 Gigaohms minimum and contact resistance of less than 100 milliohms. Ideally suited for limit sensing, security, industrial and automotive applications.

Features:

  • Capable of switching 400Vdc or 3A at up to 100 Watts
  • Minimum breakdown voltage of 600Vdc
  • Available sensitivity range of 42-83 AT

Benefits:

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

Applications:

  • Security
  • Limit switching
  • Industrial safety
