MDSR-7 12.7mm Sub-miniature Reed Switch

RoHS

Description

The MDSR-7 Reed Switch is a sub-miniature, normally open switch with a

12.70mm long x 1.80mm diameter (0.500” x 0.071”) glass envelope, capable of

switching 200Vdc at 10W. It has high insulation resistance of 10¹² ohms

minimum and low contact resistance of less than 100 milli-ohms.

Features

• Sub-miniature normally open

switch

• Available sensitivity range

10-25 AT

• Capable of switching 200V or 0.5A

at up to 10W

Agency Approvals

Benefits

• Hermetically sealed switch

contacts are not affected by and

have no effect on their external

environment

• Zero operating power required

for contact

• Excellent for switching micro-

controller logic level loads

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.
