Rated stroke - The linear or angular (as applicable) travel of the armature from the deenergized position to the
Compensated actuating voltage - The voltage that will provide at 25C 2C stabilized solenoid temperature a force
equivalent to that produced at maximum rated temperature and minimum rated voltage.
Rated force - The force in pounds a solenoid will produce at the rated stroke and minimum voltage over a specified
temperature range in accordance with the characteristic curve submitted by the manufacturer.
Rated torque - The torque in inch-pounds a solenoid will produce at a rated stroke and minimum voltage over a
specified temperature range in accordance with the characteristic curve submitted by the manufacturer.
Return force - The spring force in pounds available to move the solenoid armature and load to their deenergized
Return torque - The torque in inch-pounds available to return the armature from its energized position.
Net starting torque - The static torque produced by the solenoid within 0 percent to 5 percent of rated stroke when
rated voltage is applied.
Duty cycle - The duty cycle is the ratio of the "on" time to the total time.
Time on X 100 %
Duty cycle =
Time on + time off
Continuous duty solenoid - A solenoid that is capable of continuous operation without damage, overheating, or
malfunction when operated, with rated voltage applied, for one hour or more at a specified ambient temperature.
Intermittent duty solenoid - A solenoid that is capable of operating at the specified duty cycle without damage or
malfunction with energized periods less than one-half hour.
Direction of rotation (rotary solenoids) - Rotation is defined as clockwise when, facing the armature or power take-off
end of a solenoid, the armature moves in a clockwise direction when the solenoid is energized. When a solenoid is
energized and the armature moves in a counterclockwise direction, the rotation is defined as counterclockwise.
