Can Brickv tell me which Distance IR sensor I've got?

[JavaLaurence]

When I ordered the Distance IR briclet, I specified the "long distance" sensor from the available options:

 

GP2Y0A41: 4cm - 30cm (1.57” - 11.81”)

GP2Y0A21: 10cm - 80cm (3.94” - 31.50”)

GP2Y0A02: 20cm - 150cm (7.87” - 59.06”)

 

How can I confirm that the shipped sensor is the correct one? I'm getting readings that look more like those produced by a A41 instead of A02.

 

Can brickv tell me which sensor I've got?

 

Thx.

There is a marking in the sensor itself, you can see it here: http://www.inmotion.pt/store/images/3522.jpg

Thanks for picture. Would be nice if there was some programmatic way of determining this though. Guess there isn't..
