Solenoids
DC Solenoids for Diesel Engine Shutdown or Throttling
|
Uniquely Australian made - FDA - 3 Wire Solenoids provide reliable control over diesel engine shut down or throttling. Wired through the starter solenoid circuit or separate time delay relay the three wire circuitry avoids the problems of internally switched types. Available in 12 and 24 Volt versions and two basic sizes. All models protected from dust and moisture entry and include integral return spring.

Woodward Dual Coil Solenoids
|
To allow a solenoid to be held energized for long periods of time without overheating, Woodward uses two separate coil windings instead of one.
The first wound coil operates at a high current level to provide maximum pull or push.
The second wound coil simply holds the plunger in place after it has completed its stroke and "bottomed out."
Since the current required to hold the plunger in place is low, dual coil solenoids can be energized continuously without overheating.
This unique design concept results in a highly efficient compact solenoid approximately one half the size of a comparable single coil unit.
** all the ones in stock are 1" stroke pull type internally switched solenoids ** |

Murphy Push/Pull Solenoids
|
Murphy push pull solenoids provide single unit versatility for engine applications, such as shutdown.
A choice of two models and two voltages is available. The RP2307/2308 have 1 inch (25mm) of travel, All models come complete with a return spring and a rubber seal boot.
Both sides of the solenoid will accept 1/4 inch threaded rod. |

Engine Control
This unit has been designed to provide safe and automatic operation for the entire range of 12 or 24 volt FDA solenoids.
The pull in coil is energized for a precise period of time and the solenoid is automatically switched to the hold mode.
Burn outs to the pull in coil are eliminated due to excessive time taken in applying power. e.g. when wired to a faulty or slow starting engine via the starter relay. |

For use in conjunction with engine protection systems ie CP210F to shut off fuel.
Available in 12 volt only. |
