Notes
1) For details on electrical specifications, contact Hamlin.
2) Contact rating-Product of the switching voltage and current should never exceed the
wattage rating.
Contact Hamlin for additional load/life information.
3) Operate (inc. bounce) /Release Time-per EIA/NARM RS421A, diode suppressed coil.

4) Pull in Range-Contact Hamlin for tolerances available within this range.
5) Rating Sensitivity-The value at which contact ratings and operating characteristics ar e
determined. Derating may be required below this value.
6) Storage Temperature-Long time exposure at elevated temperature may degrade
solderability of the leads.
