Contact Power Rating - Product of the switching voltage and current should never exceed this rating. Operate (including Bounce) and Release Time - per EIA/NARM RS421A, diode suppressed coil. Pull-In Range - Contact Littelfuse / Hamlin for tolerances available within this range. Rating Sensitivity - The value at which contact ratings and operating characteristics are determined. Derating may be required below this value. Storage Temperature - Long term exposure at elevated temperature may degrade solderability of leads.
