Axial Lead Reed Switches High Power > DRR-129 DRR-129 50.8mm Close-Differential Reed Switch 07/17/2017 DRS-50 RoHS N/A 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 1010 ohms 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 • Minimum voltage breakdown 600Vdc Agency Approvals Agency Agency File Number Ampere-Turns Range E47258 E471070 42-83 AT DEMKO 14 ATEX 1393U 42-83 AT • Available sensitivity range 42-83 AT Benefits • Hermetically sealed switch contacts are not affected by and have no effect on their external environment Note: Contact Littelfuse for specific agency approval ratings. Applications Dimensions • Security • Limit switching • Capable of switching European mains voltage • Zero operating power required for contact closure • Industrial safety applications Dimensions in mm (inch) 41.27 (1.625) REF. 12.70 (.500) REF.

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 © 2018 Littelfuse Revised: 01/31/18 Specifications are subject to change without notice. littelfuse.com Axial Lead Reed Switches High Power > DRR-129 DRR-129 50.8mm Close-Differential Reed Switch Product Characteristics Operating Characteristics Operate Time 1 4.5ms - max.
