    Hi,

    I am working on a pool champion. The drop down targets are not in bank, each of them is brought back in up position with a relay (coil attracting a metallic plate). The coil ref is D355 S750, it is built with a metallic part on the top of it, which act as the magnet for the plate. The coils I have see on the market with the same ref are higher than the original one, and are not made as relays.

    Can I find the coil herewith attached, or a similar one ?

    thanks for your help

    Scroll to the bottom and you'll find cross references to Williams coils.

    yes, thanks, I know this chart, but the desired ref is not present

    If I am interpreting the pinballmedic.net chart correctly, you should be able to use another brand coil with wire size 27awg (.355mm") or greater and 750 turns.

    "When substituting another brand of coil for a Zaccaria pinball coil, it is better to go down on the gauge of wire (larger diameter wire) than change the number to turns on a coil. i.e. coil calls for 27 awg wire. However, a 26 gauge wire is the more common size, then a 26 Gauge wire should be used instead of a 28 or higher gauge wire. A large diameter wire can take more current flow without heating up then a small diameter wire. "

    I think it would be around 6K ohms if my math is correct, anyway, perhaps that gives you the right direction?

    Thanks both. I will Check. The problème I have is not only the coil, but also the metallic part which is part of the coil, in order to attract the metallic plate. Actually, this is a relay

    I have ordered a relay coil wms 27-700 which is close to the value of mine. It is just a trip relay, no time to heat. Thanks again
