DRR-DTH/DRT-DTH Features and Benefits
DIMENSIONS (in) mm
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/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 are
determined.Derating may be required below this value.
6) Storage Temperature-Long time exposure at elevated temperature may degrade
solderability of the leads.
7) Contact resistance measured at 36 Vdc, 100 ma, switched wet.
