Axial Lead Reed Switches Low Power > HA15-2 HA15-2 15.2mm Sub-miniature HV Reed Switch RoHS Description The HA15-2 Reed Switch is a sub-miniature, normally open switch with a 15.24mm long x 2.28mm diameter (0.600 x 0.090) glass envelope and capable of high voltage switching of 265Vac at 10VA. It has high insulation resistance of 10 10 ohms minimum and contact resistance less than 100 milli-ohms. It can handle light inductive loads with no suppression circuitry and switch European mains voltage. Features Sub-miniature normally Minimum voltage breakdown open switch 400Vdc (17-23AT) and 450Vdc Capable of switching 100-265Vac (22+ AT) or 0.3A up to 20VA loads outside of Available sensitivity range Agency Approvals this window is rated 10W max (see 17-33 AT Electrical Ratings) Agency Agency File Number Ampere-Turns Range E47258 Benefits 17-33 AT E471070 Hermetically sealed switch Capable of switching European contacts are not affected by and mains voltage Note: Contact Littelfuse for specific agency approval ratings. have no effect on their external Zero operating power required for environment contact closure Dimensions Dimensions in mm (inch) Applications 0.50 CL OF OVERLAP (.020) DIA.

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 and 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 lead. 6. Rating Sensitivity - The value at which contact ratings and operating characteristics are determined. Derating may be required for lower values. 2020 Littelfuse Revised: BO.12/07/20 littelfuse.com Specifications are subject to change without notice.Axial Lead Reed Switches Low Power > HA15-2 HA15-2 15.2mm Sub-miniature HV Reed Switch Product Characteristics Operating Characteristics 1 Operate Time 0.6ms - max. 1 Release Time 0.2ms - max. 2 Shock 11ms 12 sine wave 100G - max. 2 Vibration 50-2000 Hertz 30G - max.
