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) MARR-5 Switching current is limited to 1ma at 1000 Vdc. Higher voltages and currents can
be switched using correct suppression circuitry (consult Hamlin).
7) Storage Temperature-Long time exposure at elevated temperature may degrade
solderability of the leads.
