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

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.
