Axial Lead Reed Switches Low Power > FLEX-14 FLEX-14 14mm Reed Switch RoHS Description The FLEX-14 reed switch is a sub-miniature, normally open switch with a 14.00mm long x 2.28mm diameter (0.551" x 0.090") glass envelope, flexible, easily formed leads, capable of switching 200Vdc at 10W. It has high insulation resistance of 1010 ohms minimum and low contact resistance of less than 100 milliohms. Features * Sub-miniature, normally open switch * Longer leads are flexible for easy forming Benefits Agency Approvals Agency Agency File Number Ampere-Turns Range E47258 E471070 10-30 AT DEMKO 14 ATEX 1393U 10-30 AT * Hermetically sealed switch contacts are not effected by and have no effect on their external environment * Soft leads enable reliable hand forming (.872) REF. 22,15 * Office equipment * Industrial Control * Reed relays * Security * Limit switching CL OF OVERLA P (.090) MAX. 2,28 (.0185) 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, 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.
