Large Push-Pull Solenoid

Large 9-24V DC push-pull solenoid

Basically, a solenoid is an electromagnet: it is made using a large coil of copper wrapped around a frame with a metal cylinder flowing freely in the center of the coil. The metal cylinder is drawn to the center of the coil when it is energized. This allows the solenoid to pull ("pull" from one end) or to push ("push" from the other end).

This solenoid is rather nice with its still reasonable size for a much higher power (compared to our small solenoid). It has a 40mm long body and a captive frame (which traps the axis) equipped with a spring. This means that the solenoid moves the axis when it is supplied with 24V and that the return spring returns the axis to its original place when there is no more tension. It is really very practical. Many cheap solenoids are only able to push or pull the axis and have no armature trapping the axis (and the axis falls off the solenoid). Cheap solenoid also do not have a return spring.

This solenoid has 4 M3 fixing holes on its base... which makes assembly easier.

How to use

You will need a good power source to control this solenoid since a large amount of current is required to charge the electromagnet. Under 9V, the current will be about 250mA, so do not try to power it with a 9V battery! 

You will need a power transistor and a diode, as for relay mounting, but more powerful. See our tutorial for more information. .

Technical details

• "Push/pull" type with 10mm axis ejection
• Resistance of the coil (continuous): 43 ohms
• Initial force of 15 Newton (24V DC / 50% of the cycle)
• Weight: 144 grams
