Surface Mount Reed Switches  
Low Power > MDSM-4  
MDSM-4 15.3mm Surface Mount Reed Switch  
RoꢀS  
Description  
The MDSM-4 surface mount 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.  
This reed switch is a surface mount version of MDCG-4. It has high insulation  
resistance of 1010 ohms minimum and a contact resistance of less than  
100 milliohms.  
Features  
• Capable of switching 200Vdc or  
• Surface mount, normally  
0.5A at up to 10W  
open switch  
Agency Approvals  
• Available sensitivity 12-38 AT  
• Low, stable contact resistance

12-38 AT  
• 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  
Note: Contact Littelfuse for specific agency approval ratings.

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.
