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

Benefits

Agency Approvals

• Zero operating power required

for contact closure

• Hermetically sealed switch

contacts are not affected by and

have no effect on their external

environment

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.
