UK solenoid manufacturer
Dialight have been one of the leading
UK solenoid manufacturers for the last
50 years. Initially the solenoids were
developed and sold under the PED and
BLP brands.
What is a solenoid
Basically a solenoid
consists of a coil with an associated
iron circuit forming the fixed part.
A moving plunger is pulled into this
coil when it is energised. The pictures
below show a basic open frame solenoid
with a thrust pin, this solenoid can
be used as a pull type if the load
is attached at the plunger end (thick
end).
Solenoids can be
manufactured in range of sizes, frames
and mounting styles. We manufacture
a large range of open frame and tubular
solenoids.
Open frame solenoids
The diagram and picture above shows
a standard thrust (or push type), open
frame solenoid being cycled on and off.
When the solenoid is energised the PLUNGER
will be attracted to the STOP. The majority
of solenoids are open frame or 'D' frame
solenoids.
Pull and Thrust Solenoids
Solenoids have
an electromechanical pull action.
This pull action can be converted
to a pushing action by fitting a suitable
thrust pin or plunger extension as
shown above. The pull type plunger
pulls in and stops at the STOP, with
no extension coming out of the other
end.
Solenoid Voltage Requirements
Again this choice
will be predetermined by the supplies
available. A solenoid can be wound
for any voltage between the limits
of unreasonably fine wire for high
voltages and wire too thick to handle
for the very low voltages.
Where a choice is available it should
be remembered that a low voltage coil
tends to givemore power than one for
high voltage, and is more robust as
it uses heavier wire.
6, 12, 24V DC solenoids
are standards. Other DC voltages are
available as options.
Wattage - Temperature
All units in this
catalogue are designed on the basis
of a maximum allowable input wattage
without exceeding a 105ºC (221ºF)
stabilised coil temperature when operated
at the rated duty cycle in a 20ºC
(68ºF) ambient.
