59170 Series - Sub-Miniature Overmolded Reed Switch

DataSheet:Littelfuse Reed Switches 59170 datasheet

A sub-miniature overmolded reed sensor 11.43mm x 2.29mm x 2.29mm (0.450" x 0.090" x 0.090") with either straight or gull-wing leads. Provided with normally open contacts. Capable of switching up to 200Vdc at 10W. Its package contains molded stand-offs to allow board washing. Available with a range of sensitivity options, including customer-defined sensitivity. Well suited for position and limit sensing, security, and door/window alarm systems. Functions best with the 57045 actuator.

Note: The 57045 actuator is sold separately.

Features:

  • Two-part, magnetically-operated proximity sensor
  • Gull-wing or straight lead options
  • Molded stand-off to allow board washing
  • Customer-defined sensitivity
  • Suitable for reflow soldering

Benefits:

  • Well suited for usage in high-moisture and contaminated environments
  • Reed contacts last for millions of operating cycles under micro-controller voltage and current logic-level loads
  • Suitable for pick-and-place assembly

Applications:

  • Position and limit switching
  • Security
  • Door switch
