pdficon Littelfuse Reed Switches DRR-129 datasheet

pdficon 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.
pdficon 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
pdficon 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.
pdficon 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 Terms Glossary
pdficon 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?
pdficon 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).
pdficon 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.
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 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
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.
