Coil Products
We provide design, manufacturing, and evaluation services for precision coils and their applied products. We can handle prototyping and mass production. Supports various types of wires such as copper wire, aluminum wire, Litz wire, etc. Please contact us for more information.
Coil product manufacturing
Air-core coils
We offer small air-core coils. Such as round shape, square shape, etc.
(Reference) Production specifications
Inner diameter: Φ0.3 or larger
Outer diameter: Φ80 mm or less
Wire diameter: 0.025 to 1.0 mm dia.
Winding in excess of 1,000 turns is also possible.
Alignment winding and bobbin winding
Copper wire is wound on ferrite cores or plastic bobbins in alignment. We provide precision coils with perfect alignment and shape stability by self-bonding wire.
We support our customers from prototype development through cutting and injection molding of bobbins, insulation coating of core materials, film insulation, etc.
Sensor coil winding and assembly
We provide coils wound on air-core coils and ferrite cores with cable connection, encapsulation in a resin case, and assembly.
We can also provide custom-made coils for metal displacement sensors, current sensors, and eddy current testing coils.
Winding and assembly of flat coils for wireless power supply
（Production example）
Outer diameter Φ40, inner diameter Φ10
Litz wire Φ0.06 x 54 wires 27 turns
With magnetic sheet, board mounting
