Push-Pull Operation:

While physically maintaining both electromagnet and cap on same axis, the cap pulls (attracts) the electromagnet when DC power is off. The electromagnet pushes (repels) the cap when DC power is on. Most of time or default position is that the electromagnet holds the cap in a gap. When DC power is momentary on, the electromagnet exerts a repulsive force on the cap. Momentary power-on should not be more than two (2) times per minute.

DC power connection:

There are two flexible lead wires. Red connects to positive of 12 Volt DC terminal and black to negative.

DC power source concern:

Usually a push-pull electromagnet instantly takes a large amount of DC current to repel or push a cap, it is recommended to use an unregulated DC power supply that can provide a pulsed inrush current. In case of week or no pushing force, it is most likely due to using a regulated DC power supply that has current limit. It can be easily verified by using an automotive battery as DC power source.

We are developing a controlled tank circuit that stores energy before applying to a push-pull electromagnet, so that DC power source would not need to instantly deliver high inrush current.

Safety Caution:

The holding values as listed are actual readings of breaking away a 1/2" steel plate with no air-gaps between them. They have not been de-rated. For safety in holding applications, do not use electromagnets at more than 1/2 of rated value. In lifting applications, do not use at more than 1/4 of rated value. Do not use electromagnets over people.
