Magnetic Surface Mount (SMD) Reed Switch - MDSM-4 Series

Littelfuse's magnetic SMD reed switch MDSM-4 series offer zero operating power consumption to actuate the switch contacts

Image of Littelfuse's Magnetic Surface Mount (SMD) Reed Switch-MDSM-4 SeriesLittelfuse’s sub-miniature normally open (N/O) reed switches are made of glass making them hermetically sealed and will not be affected by harsh environments. They provide switching capability of 10 W at 200 VDC. The switches are actuated by a magnet and have a wide range of magnetic sensitivity options from 12 AT to 38 AT. With zero operating power consumption to actuate the switch contacts, they are ideally suited for IoT access control, security, metering, and limit sensing applications.

Features
  • 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 microcontroller logic level loads
  • Surface mount, normally open switch capable of switching 200 VDC or 0.5 A at up to 10 W
  • Available sensitivity range of 12 AT to 38 AT
Applications
  • Position sensing
  • Level sensing
  • IoT access controls
  • Industrial controls
  • Telecom
  • Office equipment
  • Home appliances
