MDSM-DT Series - 14.7mm Surface Mount Changeover Reed Switch

DataSheet:Littelfuse Reed Switches MDSM-DT datasheet

A miniature, surface mount, changeover switch with a 14.73mm long x 2.54mm diameter (0.580" x 0.100") glass envelope. Capable of switching 175Vdc at 5W. Available sensitivity range of 15-30 AT. Insulation resistance of 1 Gigaohm minimum and contact resistance of less than 100 milliohms. Available in surface mount version (MDRR-DT). Ideally suited for reed relays, security, limit sensing, telecom, office equipment and automotive applications. Available in bulk packaging or tape and reel.

Features:

  • Miniature, surface mount SPDT changeover switch capable of switching 175Vdc or 0.25A at up to 5 Watts
  • Available sensitivity range of 15-30 AT

Benefits:

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

Applications:

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