Littelfuse Hamlin Reed/Proximity Sensors

The Littelfuse Hamlin Reed/Proximity Sensors are packaged within an external housing for simplified mounting/connecting and additional protection against environmental influences. These Hamlin Reed Sensors are typically mounted in mechanical systems. A bare Reed Sensor can easily be mounted on circuit boards. However, for an application such as a door security sensor, the Reed Sensor needs a protective shell/housing for handling and mounting. These packages offer resistance to mechanical stress by protecting the bare body of the Reed Sensors.

Features

  • Choice of cable length and connector
  • Cross-slotted mounting holes for optimum adjustability
  • Customer-defined sensitivity
  • Hermetically sealed contacts
  • Magnetically-operated proximity sensors
  • Operates through non-ferrous materials such as wood, plastic, or aluminum
  • Rated for high-temperature applications up to 105°C
  • Reed contacts last for millions of operating cycles under micro-controller voltage and current logic-level loads
  • Robust construction makes this sensor well suited for harsh environments
  • Screw-down or adhesive mounting
  • Simple installation and adjustment using supplied retaining nuts
