P.S. Wilmo your signature is awesome!

The Banner Sensors you are refering to from past KOP are 2 different Models:
QS18VN6LV: Red light retro reflective sensor. These work well if you put the sensor on one side of the ball and retro reflective tape on the other side. It is visible red light so it is easy to align. This setup will work for up to 21ft (anyone remember 2002?). I use this on our backup bot.
QS18VN6D: Infra-red diffuse sensor. Sensor on one side, shiny surface on the other. Max range of 18in, I dont like these as much as you have to be much more precise with them.
More info and ordering for this line of Banner sensor is on

The Allen Bradley Photoswitch (Mark P mentions) emiter and receiver is also from a previous KOP and I am using them on our competition bot. If you like opposed sensors but dont have these, you can order QS186E and QS18VN6R from the same Banner series discussed above.
