MDRR-DT 14.7mm Miniature Changeover Reed Switch

RoHS

Description

The MDRR-DT Reed Switch is a miniature changeover switch with a 14.73mm

long x 2.54mm diameter (0.580” x 0.100”) glass envelope, capable of switching

175Vdc at 5W. It has insulation resistance of 10

ohms minimum, and contact

resistance less than 100 milli-ohms. The MDRR-DT is available in surface mount

version, that is, MDSM-DT.

Features

• Miniature SPDT changeover switch

• Capable of switching 175Vdc or

0.25A at up to 5W

• Available sensitivity range

10-30 AT

Benefits

Ampere-Turns Range

10-30 AT

• Hermetically sealed switch

contacts are not affected by and

have no effect on their external

environment

• Can be used as changeover or

normally closed contact

• Zero operating power required for

contact closure

• Excellent for switching

microcontroller logic level loads

Applications

• Position Sensing

• Reed Relays

• Industrial Controls

• Office Equipments

• Home Appliances

• Security

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.
