Axial Lead Reed Switches  
Low Power > MDCG-4  
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 1010 ohms  
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.
