Anyone using "preset counter" to stop winder?

[David King]

I've been looking at all the digital counters on ebay and a lot of them come with a relay that trips automatically when they reach a predetermined count. Some of them even have a "slow down" mode where they can trip a speed control at a predetermined count and then stop on a dime. I'm just wondering if some of you guys have experience or recommendations here.

Also are 4 digits enough? how many pickup coils need more than 9999 turns? the 4 digit preset counters seem pretty common and run a bit less...
Thanks,
David

If the counter wraps to zero on overflow I don't see an issue with 4 digits. However, 5 digit counters are convenient.

I would love to have one of those in my winder. I think the slow down feature is needed, since I would assume some winders would keep going a bit when powered down.

5 digit is best. You'll have to do math if you wind a P-90 more than 10,000 winds.:)

I'm using a Conch preset winder to stop my motor. It works wonderfully. Here are the details:
