MDSM-DT 14.7mm Surface Mount Changeover Reed Switch

RoHS

Description

The MDSM-DT Reed Switch is a miniature, surface mounting, changeover switch

with a 14.73mm long x 2.54mm diameter (0.580” x 0.100”) glass envelope. It is

capable of switching 175Vdc at 5W. The MDSM-DT has an insulation resistance

of 10⁹ohms minimum and contact resistance less than 100 milli-ohms. This reed

switch is a surface mount version of the MDRR-DT.

Features

• Surface mount SPDT

changeover switch

• Available sensitivity 15-30 AT

• Capable of switching 175Vdc or

0.25A at up to 5W

Agency Approvals

Benefits

• Zero operating power required for

contact closure

• Excellent for switching

microcontroller logic level loads

• Hermetically sealed switch

contacts are not affected by and

have no effect on their external

environment

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.
