Kuebler K07.80 7 Digit Impulse Counter Non-Resettable 5 VDC 10 mA 50 mSec pulse

Description

This is a Kuebler K07.80 counter. It might be used in vending machines, copiers, fuel pumps, or any place you want to count something. It is not resettable (but you could replace it with a new one!) And since it is mechanical, a power loss won't bother it
These are new and right out of the original packaging. In the photo, it looks like there might be a decimal point, but there's not.
If I read the data sheet correctly, it can actuate up to 10 times per second. That is a pulse of 50 milliseconds and 50 milliseconds off. Since it is inductive, I suggest putting a reverse diode across the terminals. Here is a link to the datasheet:

I will send them USPS First Class Mail with tracking. Postage will be the same for any quantity (no extra postage for 2+).
Thanks for looking!
