I believe this is the same one as listed in the BOM.
This part doesn’t have the click switch.
Use 652-PEC11-4220F-S24 or 652-PEC11-4215F-S24 (I had bought some).
Thanks for the correction! Unfortunately it came moments after I submitted my order
Ah, so I saw the “ordering information” section in the datasheet and decoded your part number. It has a switch, it clicks, it has a flatted shaft. So all’s well that ends well.
Looks like the encoders spec’d are now “obsolete” and only available in limited quantity from Farnell. Any idea what a suitable replacement would be?
This looks like the closest match in the Mouser catalog now:
There’s a few others with similar specs, but not in stock.
