Technical Resources
- Sensing Products Selection Guide
  This guide provides an introduction to magnetic sensing and options for value-added custom design packages.
- Flow Sensing in Tankless Water Heaters Application Note
  Reed switches and sensors are highly effective solutions for flow sensing applications that can be used for detecting the presence of fluid flow in a system or even measure the rate of fluid flow.
- Position and Level Sensing in Washing Machines
  A most integral appliance in any home is a washing machine. Washing machines have helped made the chore of cleaning clothes quite effortless.
- Rice Cooker Lid Lock Application Note
  The position sensing lid lock ensures that the lid is securely locked in place.
- Capacitive Loads Application Note
  When there is significant capacitance in a reed sensor reed relay or reed switch circuit the peak current and energy switched by the reed contacts should be considered.
- Inductive Load Arc Suppression Application Note
  When a reed switch or reed sensor is used to control an inductive device (relay coil solenoid transformer small motor etc.)
- Reed Switch and Reed Sensor Activation Application Note
  Although a reed switch can be activated by placing it inside an electrical coil many reed switches and reed sensors are used for proximity sensing and are activated by a magnet.
- Reed Switch Extended Shock Capabilities Application Note
  The maximum shock specifications in the Littelfuse catalog are very conservative for most switches smaller than the DRxxxx type. T
- Vibration Testing and Precautions Application Note
  Littelfuse tests sinusoidal vibration according to Mil. Std. 202G Method 204D Test Condition G (10 � 2000 Hz frequency sweep at 30 G or 0.06 inch double amplitude whichever is less).
