AC Linear Solenoids

Open frame linear solenoids ideally suited

for AC applications, having the frame and

the

construction, featuring high permeability

and low magnetic losses. They are

designed to be operated in any position,

being able turning an electric pulse into an

axial pull action. Coil winding insulation

being in Class F. Performance, as shown

in the following diagrams, is always

referred to a temperature rise of 80°C in

open air, with 35°C ambient temperature

and coil fed at 105% of rated supply

voltage (as per VDE 0580). Since the

mechanical

ON and OFF times corresponding to

relative duty factors lower than ED=100

result, for standard ED values, from the

following diagram:

Current values given in our diagrams are

at nominal voltage. Forces shown are

referred to solenoids fed @ 90% of rated

voltage, with ‘hot’ coil and 20°C ambient

temperature.

Any AC solenoid, due to its high power

consumption (VA), will rapidly overheat

and fail to operate, whenever its plunger is

prevented from seating properly. To avoid

this, a proper spring can be interposed

between plunger and application. When

adopting a solenoid please also bear in

mind what follows:

1) Any load should be always applied

strictly along the plunger main axis (to

avoid excessive wear due to friction, and

noise

generated by the AC power supply).

2) Any mechanical stroke-limiting device

eventually provided, should be made of

non magnetic material.

solenoids is a constant, any amount of

that force eventually not utilised by

relevant application will be expended

under form of impact force. Consequently,

any application should correctly use the

smallest available solenoid performing the

required

maximum

temperature. To select the right solenoid,

an exact determination of the duty cycle is

equally essential: whenever the maximum

cycle is exceeding 300 seconds, a

continuously rated solenoid (ED=100)

should be used. Otherwise the relative

duty factor would result as follows:

3) The expected life of a solenoid would

be remarkably increased as much as its

impact force could be absorbed by the

solenoid mounting frame.

When a continuously rated (ED=100)

solenoid is required but space is not

enough, a resistor and/or a limiting

impedance could be used to feed a

smaller

(ED<100). Models NT1 and NT2 are

supplied with built-in fixing brackets, while

models NT3 and NT4 have no bracket,

even if these are available as a separate

optional kit (for mounting on left, right or

lower side position, as required).
