MDCG-4 15.3mm Sub-miniature Reed Switch

RoHS

Description

The MDCG-4 Reed Switch is a sub-miniature, normally open switch with a

15.24mm long x 2.28mm diameter (0.600” x 0.090”) glass envelope, capable of

switching 200Vdc at 10W. It has high insulation resistance of 10¹⁰ohms

minimum and contact resistance less than 100 milli-ohms. This reed switch is

also available in a surface mount version, that is, MDSM-4.

Features

• Sub-miniature normally

open switch

• Capable of switching 200Vdc or

0.5A at up to 10W

• Available sensitivity 12-38 AT

Agency Approvals

Benefits

• Zero operating power required for

contact closure

• Excellent for switching micro-

controller logic level loads

• 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.
