	Littelfuse Reed Switches MASM-14 datasheet
	Soldering Temperatures Application Note This application note applies to all of Littelfuse?s products that are normally soldered to printed circuit boards (PCBs) including all reed switches.
	Extreme Temperature Reed Switch Operation Application Note Littelfuse reed switches are normally specified to operate in a temperature range of -40 ?C to +125 ?C. T
	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.
	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.)
	Catalog Glossary Reed Switch Terms Application Note Reed Switch Terms Glossary
	Ampere turn versus mT and Gauss Application Note What is the relationship between AT (Ampere*turn) and Tesla or Gauss? What magnet strength will activate a 15 AT reed switch at 5 mm?
	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).
	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.
	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
	Rice Cooker Lid Lock Application Note The position sensing lid lock ensures that the lid is securely locked in place.
	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.
	Handling of Reed Sensors Relays And Switches Application Note When used within their capabilities Littelfuse reed sensors reed relays and reed switches provide many years of robust performance
	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.
	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.
	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.
