low profile quadrature encoder

[BobW55]

I am looking for a very low profile encoder to go on the end of a motor shaft. I only have about 1/4" of end shaft to hook on to. I can mount a pulse wheel no problem but only have limited space between the motor housing and the wheel. Any ideas?

I am also looking at the possibility of using a shaft mounted encoder with a gear drive.

As always, the devil is in the requirement details. What type of encoder resolution and output do you need?

[BobW55]

20 pulses per rev would be more than enough, no matter if I use the motor end or a shaft/gear drive.
Will have to post a picture of the motor end, would explain better then words.

Perhaps an opto interrupter would work.

Low profile.
