DRR-129 Series - 50.8mm High Voltage Reed Switch
DataSheet:Littelfuse Reed Switches DRR-129 datasheet
A standard, normally open switch with a 50.80mm long x 5.25mm diameter (2.000" x .207") glass envelope, capable of high voltage and power switching up to 400Vdc at 100W. It is rated to carry 6A and switch 3A. Available sensitivity range of 42-83 AT. High insulation resistance of 10 Gigaohms minimum and contact resistance of less than 100 milliohms. Ideally suited for limit sensing, security, industrial and automotive applications.
Features:
- Capable of switching 400Vdc or 3A at up to 100 Watts
- Minimum breakdown voltage of 600Vdc
- Available sensitivity range of 42-83 AT
Benefits:
- Hermetically sealed switch contacts are not affected by and have no effect on their external environment
- Capable of switching global mains voltage
- Zero operating power required for contact closure
Applications:
- Security
- Limit switching
- Industrial safety
