OEM Large push-pull solenoid Solenoid 24V

Electromagnets are essentially electromagnets: they consist of a large coil of copper wire with an armature (a metal lump) in the center. When the coil is energized, the lump is pulled into the center of the coil. This allows the magnet to pull (from one end) or push (from the other side).

Specifically, this magnet is nice and strong, with a 40 mm long body and a "captured" armature with a return spring. This means that when activated with up to 24 VDC, the magnet moves and, when the voltage is removed, it springs back to its original position, making it convenient to use. Many cheaper magnets are either push type or pull type only and are not allowed to have a captured armature (it will fall out!) or lack a return spring. This magnet has 4xM3 (metric) threaded holes on the bottom for easy mounting.

To control an electromagnet, you will need a power transistor and a diode. Use the included schematic for wiring with an Arduino or another microcontroller. You will need a fairly good power supply to operate an electromagnetic valve, as a lot of current flows into the solenoid to charge it, about 250 mA. So do not try to power it with a 9 V battery!

Technical details:

• 24 DC operation (you can use 9-24 DC volts, but lower voltages will result in weaker/slower operation)
• Push or pull type with 10 mm stroke
• Coil resistance: 43 Ohms
• 15 Newton starting force (24 VDC / 50% duty cycle)
• 5.1 ounces / 144 grams.
