Description
The MRPR-3 Reed Switch is a miniature, normally open switch with a 19.69mm
long x 2.84mm diameter (0.770” x .112”) glass envelope, capable of switching up
to 200Vdc at 50W. The MRPR-3 has high insulation resistance of 10¹⁰ ohms
minimum and contact resistance less than 100 milli-ohms.
Features
• Miniature normally open switch
• Switch contacts capable of
switching 200Vdc or 1.5A at
up to 50W.
• Available sensitivity range
22-43 AT
Benefits
• Hermetically sealed switch
contacts are not affected by and
have no effect on their external
environment
• Zero operating power required
for contact
• Power switching with a
miniature switch
Applications
• Limit Switching
• Telephone Line Switching
• Office Equipments
• Heavy Load Switching
• Light Inductive Loads

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
