Bartosz,

I was unable to find the particular number of which you are iinterested. However, I am aware of similarity between the Agilent numbering system and the number you listed. Perhaps what you have is an item which Agilent designed, but does not sell for outside the company.

I suggest you direct your browser to -

http://www.agilent.com

Then find the semiconductro products link and drill don through it until you find Motion Control. There you will find datasheets for ICs, encoders and other interesting stuff. The style of encoder you have is, I think, a housed encoder of the quick assembly style.

Also, I think the part number prefix 'QEDS' might be listed in the Agilent site as 'HEDS'.

Good Luck,

Bruce
