Description
The MARR-5 reed switch is 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 1kVdc at 1mA. It has high insulation resistance of 10¹² ohms
minimum and contact resistance less than 100 milli-ohms.
Features
• Miniature normally open switch
• Capable of switching 1000Vdc at
1mA or 0.5A up to 10W
• Minimum voltage breakdown
2000 Vdc
• Available sensitivity range 17-38 AT

environment
• Zero operating power required
for contact closure
Applications
• Reed relays (particularly suitable
for high voltage breakdown
applications)
• Security
• Limit switching
• Telecoms line switching
• Office equipment

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.
