HA15-2 15.2mm Sub-miniature HV Reed Switch
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.

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 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.
