A sub-miniature, surface mount, close-differential, normally open switch with a 14.00mm long x 2.28mm diameter (0.551" x 0.090") glass envelope capable of switching 200Vdc at 10W. Available sensitivity range of 10-30 AT. High insulation resistance of 1010 ohms minimum and low contact resistance of less than 100 milliohms. Available in axial-leaded version (MACD-14). Ideally suited for position, proximity, float position sensing for liquid level, industrial controls, office equipment, home appliance, and telecom applications.

Features:

  • Low close/open hysteresis (close differential)
  • Surface mount normally open switch capable of switching 200Vdc or 0.5A at up to 10 Watts
  • Available sensitivity range of 10-30 AT

Benefits:

  • Hermetically sealed switch contacts are not affected by and have no effect on their external environment
  • Zero operating power required for contact closure
  • Excellent for switching micro-controller logic level loads

Applications:

  • Position sensing
  • Security
  • Level sensing
  • Industrial controls
  • Office equipment
  • Home appliances

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

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.
