FWIW, the Rockwell catalog for the 42EF model sensor lists the "Response Time" as "1 to 16 ms".

It's not clear whether those numbers mean

a) the pulse width must be 1 to 16ms in order to be reliably detected, or

b) it takes the sensor 1 to 16ms to respond to a pulse (and the required pulse width is left unspecified, or

c) something else.

You need the stripe width to be 1/12 of a revolution at the point of sensing in order for it to be under the sensor for 1ms when the wheel is spinning at 5000 rpm.
