I generally like to see a lower value of pullup resistor than the 2.2k which
is used in the above sensor kit, but at least some people have gotten it to
work as-is. We prefer industrial inductive proximity switches from, e.g.,
Automation Direct (a couple of part numbers are given on the FAQ page on our
website... *cough-cough*) as they are robust, immune to external magnetic
fields, and very inexpensive ($20-$25). You do need to supply the mounting
bracket and target for them, though, so they are not nearly as convenient as
the above sensor kit.
One of our customers just did a nice video covering the setup and testing of
the exact same tach sensor. He also had some difficulty with it along the
way but it seemed to be working as expected during the shooting of the
Finally, posting your technical support questions to the EVDL and hoping
someone from Evnetics sees them is not nearly as effective as actually
emailing us directly...
