Everybody has the same one-page data sheet that doesn't give enough info to create a specific part number, or even interpret part numbers that are stocked by distributors. So, I have pretty much given up on them. Also, I was very lucky to finally spot a note that their 1000 and 1024 line HKT30-series encoders do not have index.
Seems like the next best thing is the US Digital E2-1000-250-I-D-D-B, at $62 in single quantity. Has anybody used the E2 series in EMC applications? I worry that they might need additional capacitors to be added to the read head. They even have a note in the data sheet to not use them with more than 6 feet of cable without using their $16 line driver (which they also note adds a 0.1 uF capacitor to the encoder.)

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2d-c2 _______________________________________________ Emc-developers mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-developers
