For details on electrical specifications,contact Hamlin,Inc . 2) Contact rating-Product of the switching voltage and current should never exceed the wattage rating. Contact Hamlin for additional load/life information. 4) Pull in Range-Contact Hamlin for tolerances available within this range . 5) Rating Sensitivity-The value at which contact ratings and operating characteristics are determined.Derating may be required below this value. 6) Storage Temperature-Long time exposure at elevated temperature may degrade solderability of the leads. 3) Operate/Release Time-per EIA/NARM RS421A,diode suppressed coil.
