Design Considerations

Life

When selecting an

open frame solenoid, as

with any other solenoid

style, it is important to

consider the effects of

heat, since an increase in

coil temperature reduces

the work output and the

life of the unit. Standard

life is 50,000 to 100,000

operations. Consult

the factory for longer

life of 500,000 or more

cycles, and other special

requirements.

Duty Cycle

Duty cycle is determined

by solenoid ON time/(ON +

OFF time).

For example: a solenoid

is actuated for 30 seconds,

then off for 90 seconds.

30 sec ON / (30 Sec ON + 90

sec OFF) = 30/120 = 1/4 or

25% duty cycle.

Performance Curves

The Force/Stroke

performance curves in this

section serve as guides to

determine the solenoid

size needed to produce

a desired force at a

given stroke, duty cycle,

and power source. All

Force/Stroke curves are

performed under standard

test conditions: ambient

temperature of 20°C. A

design safety factor of 1.3

to 1.5 is recommended.

For example, when a 4.5 lb

pull force is required,

select a model with a

safety factor of 1.3 to 1.5

times (5.8 to 6.7 lb).
