Custom Coil Solution
BOTH LEADS EXIT THE OUTSIDE OF THE COIL
At Precision Econowind, we recently helped a customer who needed a very small coil manufactured. This was very thin dimensionally, similar in size and shape to a quarter, with a hole in the center leaving about 1/8th inch of the rim. It was designed for use as an antenna that would fit laminated between two plastic sheets, to make a type of “smart card”. The greatest challenge of this project was in meeting the narrow dimensions required for the coil.
The customer specified electrical criteria were met by using #38 AWG bondable wire which is just under .005” in diameter. The allowable space in which the coil had to fit was .010” and a coil two wire diameters thick would allow for enough turns. However, the inside lead wire, which is the start-of-winding wire, had to cross over the windings, and there was not room for that one strand. Even though it just crossed over from inside to outside, in one area, that one strand actually made the coil three wire diameters thick.
We were able to solve this problem, with an innovative
