Latching Solenoids

Our latching solenoids utilize a permanent magnet in conjunction with the solenoid coil to maintain the position of the plunger with no current applied. The latching solenoid can perform push, pull, hold and release operations with only an instantaneous pulse of current, thus offering a significant power-saving efficiency and maximum life. Latching solenoids are also found in bi-directional magnetic latching open frame versions. These models electromechanically power the load in both directions, and hold it magnetically latched in either position indefinitely, without power. These features make a latching solenoid ideally suited to continuous duty applications, since even without power, the armature and load will remain latched in the energized position. Applications for latching solenoids include automatic door closers, locks, latching mechanisms, medical equipment, security devices, and battery powered equipment.

Push Pull Solenoid

What is a push-pull solenoid?

Although similar, a push-pull solenoid is two separate styles of a solenoid. Their type is determined by which end of the plunger is used to attach the load & provide the desired movement. They develop force in one direction when energized.

Pull Solenoids

A pull solenoid features the attachment at the end of the plunger that is moving into the coil and away from the load. When power is applied to the coil, a magnetic field is created that attracts or pulls the plunger into the coil toward the solenoid’s base or bottom. Attaching at the end of the plunger means it will pull the load toward the solenoid.

Push Solenoids

A push solenoid is a pull solenoid with an added shaft that extends out of the bottom of the solenoid plunger to provide a pushing function. The added shaft is a non-magnetic material and is generally press-fit into a hole at the end of the plunger. The smallest shaft end features the attachment as it is the end that moves away from the solenoid, allowing the load to be pushed away.  

How does a pull solenoid work?

A pull solenoid is essentially an electromagnet. It contains a big coil of copper wire inside with an armature of metal in the middle. When the coil of wire is energized, the armature is pulled into the coil’s center. Allowing the solenoid to pill from one end or push from the other.

What’s the difference between an electromagnet and a solenoid?

While both are similar, an electromagnet is an electrically induced magnet that has a core of magnetic material (such as iron) encased in a coil of wire. An electrical current is passed through to magnetise the core. Whereas a solenoid is a coil of wire acting as a magnet during interaction with an electric current. Essentially they are the same, but the solenoid doesn’t have a core of material and doesn’t have as strong a magnetic field as an electromagnet.
