These coils are my best alternative, as well as trying to keep the cost down.
Currently I'm capable of producing two different coil sizes,
but I am
working on producing a larger one also.
1) Approximate 7/8 inch ID, 4 inch OD and
wound with a 20 1/2 AWG wire.
Aprox 50 Turns
Inductance, aprox 125 uhy
measured at 1 Khz.
DC Resistance aprox 0.5 ohms.
It Detects a Quarter at
about 5" And a pop can at about 13", on my unit.
This Smaller coil is $15.00 USD Plus Postage
2) An Approximate 3.75 inch ID, 7 inch OD
and wound with a 20 1/2 AWG.
Aprox 50 Turns
Inductance, aprox 435 uhy
measured at 1 Khz.
DC Resistance aprox 0.8 ohms.
It Detects a Quarter at
about 7" And a pop can at about 17", on my unit.
This Larger coil is $30.00 USD Plus Postage
3) Now Also
Available!
Larger "Flat" type coils, Possibly up to 12
inches
Inquire as to the OD Size and Turns you would like and the Wire Size
you wish it to be.
I now have both 18 1/2 AWG and 20 1/2 AWG Wire.
***************************************************************************
WHY 18 1/2 or 20 1/2 AWG? I got a good deal on the price of this wire!
These coils are wound with one turn per layer within the Approximate dimensions above!
And they are wound in a Shallow Cone Shape to give them added strength and regidity.
NOTES:
Postage Costs Will Vary, depending where you live!
Orders recieved from outside of Canada are subject to Duty and Tax as May be Imposed by that Countries various Customs Officals!
Sorry, I have no control over this and I do not want to get in trouble with the governments involved! But usually this is only a few dollars at most!
*** Additionally, I'm am working on getting another coil made by a
company I deal with. It is to be "Pi" wound. ("Pi Winding" is a Unique
Criss-Cross Winding Pattern that Reduces Capacitance in a multi-layer
coil!)
If it works out as I'm hoping it will, I will be able to produce a
good coil, quite reasonable in price!
Enquire by E-mail for details!
