Product Specifications

Technical details and manufacturing context for Transmitter Coil Assembly

Definition
The Transmitter Coil Assembly is a critical electromagnetic component within an Industrial System that generates oscillating magnetic fields or transmits electrical signals through inductive coupling. It serves as the active transmitting element in systems requiring wireless power transfer, proximity sensing, data communication, or inductive heating by converting electrical energy into controlled electromagnetic radiation.
Working Principle
When electrical current flows through the wound conductor of the coil assembly, it generates a time-varying magnetic field according to Ampère's law and Faraday's law of induction. This electromagnetic field propagates through space or couples with nearby receiver coils, enabling energy transfer, signal transmission, or inductive effects without physical contact. The assembly's physical construction (coil geometry, winding pattern, core material) determines the field characteristics, efficiency, and operating frequency range.
