Air core Coil
Medium Vertical Round Air Core Coil, Thick Multi-Layer Enameled Copper Winding, High Magnetic Flux Inductor For Medium NFC Readers & General Wireless Charging Devices.
Product Overview
This medium-sized vertical circular air core coil is formed by dense multi-layer self-bond enameled copper wire without magnetic core. Moderate outer diameter balances sensing distance and installation space, thick winding layers greatly improve magnetic field strength, fine thin leads support easy PCB soldering.
Core Advantages
- Medium vertical thick winding: Higher inductance and stronger magnetic field than miniature coils for longer detection range
- Hollow circular center hole: Reserved positioning hole for fixed installation and shaft matching
- Air-core design: Eliminate magnetic saturation and hysteresis loss, stable performance under long-time operation
- High-purity copper material: Low DC resistance, low heat generation and high energy transfer efficiency
- Fully customizable: Outer diameter, inner aperture, winding turns, wire gauge and lead stripping length adjustable
