DRR-129 50.8mm Close-Differential Reed Switch

RoHS

Description

The DRR-129 Reed Switch is a standard, normally open switch with a 50.80mm

long x 5.25mm diameter (2.000” x .207”) glass envelope, capable of high voltage

and power switching up to 400Vdc at 100W. Will carry 6A and switch 3A. It has

high insulation resistance of 10¹⁰ohms minimum and contact resistance of less

than 100 milli-ohms.

Features

• Normally open switch

• Capable of switching 400Vdc or

3.0A at up to 100W

• Available sensitivity range

42-83 AT

• Minimum voltage breakdown

600Vdc

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
