Product per for mance may be affected by the application to which t he
product is applied. Upon request, HAMLIN will assist purchaser s by
providing infor mation specific to any par ticular application. HAMLIN
disclaims any and all liability whatsoever for any purchaser ’s reliance

Notes 1) Contact rating-Product of the switching voltage and current should never exceed the
wattage rating. Contact Hamlin for additional load/life information.
2) Operate (inc. bounce) /Release Time-per EIA/NARM RS421A, diode suppressed coil.
3) Pull in Range-Contact Hamlin for tolerances available within this range.
4) Rat ing Sensitivity-The value at which contact ratings and operating characteristics are
determined. Derating may be required below this value.
5) Storage Temperature-Long time exposure at elevated temperature may degrade
solderability of the leads.
