MLRR-3 15.2mm Miniature Close Differential Reed Switch

RoꢀS

Description

The MLRR-3 Reed Switch is a miniature, normally open switch with a 15.24mm

long x 2.54mm diameter (0.600” x 0.100”) glass envelope, capable of switching

200Vdc at 20W with close differential (CD) characteristics. 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, MLSM-3.

It can handle light inductive loads.

Features

• Miniature normally open switch

• Capable of switching 200Vdc or

01.0A at up to 20W.

• Close differential AT between PI

and DO value

• Maximum switched current of

1.0Amps

• Available sensitivity range 17-38 AT

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.
