MARR-5 Series - 19.7mm Reed Switch
DataSheet:Littelfuse Reed Switches MARR-5 datasheet
A miniature, normally open switch with a 19.69mm long x 2.66mm diameter (0.775" x 0.105") glass envelope. Capable of high voltage switching of up to 1000Vdc at 1mA. Available sensitivity range of 17-38 AT. High insulation resistance of 1012 ohms minimum and contact resistance of less than 100 milliohms. Ideally suited for reed relay high breakdown voltage applications, security, metering, limit sensing, telecom and office equipment and automotive applications.
Features:
- Normally open switch capable of switching 1000Vdc up to 1mA
- Minimum breakdown voltage of 2000Vdc
- Available sensitivity range of 17-38 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
Applications:
- Reed relays
- Security
- Limit switching
- Industrial controls
- Office equipment
- Telecom
