Description
The DRS-50 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 2mA. Will carry 6A and switch up to
100W/VA. It has high insulation resistance of 1010 ohms minimum anontact
resistance of less than 100 milli-ohms.
Features
• Normally open switch
• Capable of switching 400Vdc or
3.0A at up to 100W
• Availsitivity range

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
