What is a latching solenoid

Latching solenoids, or latching solenoids, are special electromagnet devices that can switch and maintain between two stable states without continuous power supply. Its working principle is based on the interaction between electromagnetic induction and permanent magnets. When the coil of the latching solenoids is energized, the magnetic field generated interacts with the magnetic field of the permanent magnet, thereby pushing the internal moving parts (such as the valve core or armature) to move to another position. Once the moving part reaches the new position, even if the coil is powered off, the moving part will remain in that position due to the magnetic force of the permanent magnet, achieving a latching effect. When it is necessary to switch back to the original state, just energize the coil again, but the direction of the current is opposite to the last time, and the moving part can be pushed back to the original position.

How we work

Designing

Design the electromagnet according to the requirements, mainly considering the voltage and current, functional requirements, shape and appearance of the electromagnet. Excellent design makes product production smooth

electromagnet coil electromagnet core materials

electromagnet coils

The coil manufacturing of the electromagnet uses insulated wire or insulated copper wire, and uses mechanical or automated equipment for precision winding.

Prepare Accessories

The main accessories include electromagnet slide bar, electromagnet housing, wires, springs, etc.

Assembly

The last key link in the manufacturing journey of electromagnets is the finished product assembly. This stage brings together many parts such as the wire package, slide rod assembly, and housing, which are assembled mechanically or manually to form a complete and high-performance electromagnet product.

Electromagnet testing

After the finished product is assembled, the electromagnet must undergo a series of rigorous tests to ensure that its performance and quality meet the standards. Only electromagnets that successfully pass all tests can be officially recognized as qualified products.

Packaging

Once the electromagnet passes all the tests, it will be carefully packed into a plastic box and tightly sealed by blister or sealing technology to ensure its safety and integrity during transportation. These products will then be properly placed in pre-selected boxes and clearly identified with corresponding labels.
