20 c/s is 50 ms ... 3 cycles are 150 ms ...
electronics works for 80 ms per 3 cycles ...
SO ... if your switch is a good quality / low inertia one... it Works !!! 
but, of course ... if it works in oil ... ( gear box ...)
magnetic detector looks to be THE thing ... I think telemecanique also have nice proximity switches that can reach 50 or 100 Hz ... ( I have some home ...)
at least it's no more an electronics problem ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
