Compact Magnetic Reed Sensor 59022 Series

Littelfuse’s reed sensor 59022 series is available with a range of sensitivities, cable lengths, and connector options

Image of Littelfuse 59022 Firecracker SeriesLittelfuse’s 59022 series reed sensor is a compact, cylindrical, magnetically operated sensor capable of switching up to 265 VAC / 300 VDC at 10 W/VA. The sensor capsule’s diameter of just 5.80 mm (0.228 inches) makes it easy to install in confined spaces of existing structures. It is designed for use with the matching 57022 actuator, which is sold separately. Circuit designers have the flexibility to choose from normally open, normally closed, or changeover contacts.

Handling of Reed Sensors, Relays, & Switches

Features and Benefits
  • 25.4 mm x 5.80 mm form-factor
  • Magnetically operated proximity sensor
  • Hermetically sealed contacts
  • Operates through non-ferrous materials, such as wood, plastic, or aluminum
  • Available with normally open, normally closed, or change-over contacts options
  • Customer-defined sensitivity
  • Custom cable length and connector options
  • Fits easily into small, confined spaces
  • Quick and easy to install
  • Well suited for usage in high-moisture and contaminated environments
  • Non-contact solution; aesthetically more appealing than push button or lever mechanical-type switches
  • Ideal for battery-powered applications because the contacts do not draw power when in the non-activated state
  • Excellent for switching micro-controller logic level loads
  • Uniquely designed for customers’ specific application requirements
