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.
pdficon 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
pdficon Rice Cooker Lid Lock Application Note

The position sensing lid lock ensures that the lid is securely locked in place.
pdficon Storage of Littelfuse Sensor Parts Application Note

The data sheets for Littelfuse parts show temperature ranges for storage. However long term exposure to extreme temperatures in the specified storage temperature range may degrade solderability of terminals.

pdficon Measuring Reed Switch Sensitivity and Contact Resistance Application Note

The purpose of this application note is to document the preferred method of reading the sensitivity and contact resistance of Littelfuse reed switches.
pdficon 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.
pdficon Modifying Reed Switches Application Note

When cutting and forming reed switch leads it is important to use the correct support and cutting tools to avoid causing damage to the glass-to-metal hermetic seals.
