Understanding coils
« on: August 22, 2010, 10:16:46 PM »
Hi Guys

I'd like to replace one of the coils in a Data East machine i have. If I get a Data East one then its simple to change over same for same by part number, but if I was to purchase a different brand I need to under stand how to read the numbers on the coil. !@# The coil I want to change is a 090-5005 Data East number, but looking at a spares web site they list different brands and each brand has its own nmbers.

Does anyone have a link to a web site that explains coil sizing or is someone able to give me a run down of how to do this.

Thanks Mark.

Cheers Mark.

with  williams pinball coils the first number is the gauge of wire used and the second number is the amount of turns, i.e a 23-800 has 23 gauge wire and 800 turns

your coil 090-5005  is equal to a 23-840

the closest coil i can find is a stern 23-840 http://www.marcospecialties.com/product.asp?ic=090-5005-00

here are the specs for the coil
 Wire Gauge: 23
 Number of turns: 840
 Resistance in ohms: 4
