Consumer Electronics & Wearables
Charging and sensing modules for compact connected products.
Custom Electronic Coils
Product Overview
Sensync’s custom electronic coils are developed and manufactured according to customer drawings, samples, technical specifications, or application requirements. Skip the guesswork of sourcing coils from a catalog. Send us your drawing, sample, or specification, and we can develop a coil around your actual application requirements. Supported by our own winding equipment and manufacturing processes, production yield can reach up to 99.9% depending on the approved product and production conditions. From first sample to mass production, customers work with one team throughout.
Our product range covers wireless charging coils, RFID / NFC sensing coils, air-core inductor coils, and other related electronic coil types. Products can be developed according to different requirements for dimensions, wire diameter, number of turns, inductance, structural form, mounting space, and application requirements, and are used in consumer electronics, wearable devices, automotive electronics, IoT, smart-home products, and industrial electronics.

Customized Electronic Coils
Have a coil requirement that does not fit a standard product category? Sensync works directly from your drawings, samples, or technical brief to develop and manufacture coils tailored to the required structure, dimensions, wire diameter, number of turns, inductance, lead configuration, and mounting method. Whether you need a prototype for validation or stable supply for mass production, we support the project from first sample through volume delivery.
Customization Capabilities
To meet different product requirements, we provide customization support for the following aspects:
- Customization of outer diameter, inner diameter, height, and coil shape
- Customization of wire diameter, wire type, and winding method
- Adjustment of number of turns, inductance, and related electrical parameters
- Development of single-layer, multi-layer, flat winding, random winding, and special structures
- Optimization based on installation space, module structure, and end-product requirements
- Support for development based on drawings, samples, technical specifications, or application requirements
For different project stages, we can provide support from sample evaluation and process validation to mass production, helping customers move forward more efficiently with product validation and production introduction.
