DRR-129 50.8mm Close-Differential Reed Switch
RoHS
Description
The DRR-129 Reed Switch is 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. Will carry 6A and switch 3A. It has
high insulation resistance of 1010 ohms minimum and contact resistance of less
than 100 milli-ohms.
Features
• Normally open switch
• Capable of switching 400Vdc or
3.0A at up to 100W
• Minimum voltage breakdown
600Vdc

Notes:
1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information.
2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and AN107 for details.
3. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load.
4. Breakdown Voltage - per MIL-STD-202, Method 301.
5. Storage Temperature - Long time exposure at elevated temperature may degrade solderability of the leads
