MDRR-DT Series - 14.7mm Changeover Reed Switch
DataSheet:Littelfuse Reed Switches MDRR-DT datasheet
A miniature 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 (MDSM-DT). Ideally suited for reed relays, security, limit sensing, telecom, office equipment and automotive applications.
Features:
- Miniature 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
