Here is the datasheet for these, http://pewa.panasonic.com/assets/pcsd/catalog/napion-catalog.pdf

Curious about these. I like the size of it and that all the circuitry is internal with only 3 pins showing. Looks like they can be ordered with digital and analog output, use 5VDC power, and low current requirements.

Can anyone who has used any of these comment on it's sensitivity? Are they pretty reliable?

I've used the one from Sparkfun but looking for something smaller with smaller range.This line of sensors has 2m, 5m and 10m models.

I've also use the parallax one, but I find it is hard to mount and use in a practical manner and it's extremely sensitive and goes off too much for my liking. Sometimes even when there is nothing in front of it.

Si

No, but it looks interesting.

Is it by any chance 'use an unusual IR sensor day' today?
