Features:
1. Pull style, rectilinear motion,DC solenoid ,DC electromagnet.
2. It used for security products, security cabinet,intelligent door lock, automatical equipment, beauty device,toy,machine,etc.
3. It work by pushing the plunger outward.
4. When energized,working by pulling the plunger to connect the object.
5.Do not exceed the rated parameters by 5%.
6. All material ROHS approved.
7. Mechnical lifespan: Over 500,000 times.
Electromagnets must meet the following conditions to achieve maximum suction:
1,The object to be sucked must have a good magnetic permeability.
2,Proper use of power supply, rated voltage.
3,The object to be sucked must be flat and clean.
4,The object to be sucked must be greater than or equal to the surface of the magnet
( For example: the magnet is 20*15 mm , so the surface area is
S=r²π=10²π mm²
so the object to be sucked must be greater than or equal to 10²π mm² )
5,The object to be sucked must be greater than 8mm.(If the thickness decreases, the suction decreases)
6,The object to be sucked must be close, the middle can't be interspersed with objects or gaps
We have equipment:
High precision hydraulic machine, punching machine, stamping machine, Automatic rubber coating Machine ,coil winding machine,Riveting machines 
What we know: A long straight coil of wire can be used to generate a nearly uniform magnetic field similar to that of a bar magnet. Such coils, called solenoids, have an enormous number of practical applications. The field can be greatly strengthened by the addition of an iron core. Such cores are typical in electromagnets.
