Well, had to be interested in that since I used to supply one 25 years ago, so off to read the web site.
Frstly, after about 10 minutes it demanded I log into the web site, and when I declined it threw me off, never come across this before, some problems?
Secondly, what I was looking for was some details of boring things like accuracy, resolution, repeatability, you know, how useful is it. All I could find was a resolution of 2 microns, really? Nothing else. Read my details and these trivial details were displayed for all to see.
Seems if you fit the bolt on version you lose some, not stated, tailstock movement to the right of the saddle. It was obvious to me that this was not a good idea, must be now, who wants to machine their cross slide.
Sensor thickness less than 2mm, mine was 0.5mm, just a piece of stainless wire.
I will still repair my sensors, after 35 years, any competition there?
Not impressed.
