MDSR-7 Series - 12.7mm Reed Switch
DataSheet:Littelfuse Reed Switches MDSR-7 datasheet
A sub-miniature, normally open switch with a 12.70mm long x 1.80mm diameter (0.500" x 0.071") glass envelope. Capable of switching 200Vdc at 10W. Available sensitivity range of 10-25 AT. High insulation resistance of 1012 ohms minimum and low contact resistance of less than 120 milliohms. Ideally suited for reed relay applications, security, metering, limit sensing and telephone off-hook applications.
Features:
- Normally open switch capable of switching 200Vdc or 0.5A at up to 10 Watts
- Available sensitivity range of 10-25 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:
- Reed relays
- Security
- Limit switching
- Industrial controls
- Telecom
