Has anyone tried using a magnetic sensor such as a crankshaft position sensor for a spindle encoder? I would not have to protect this arrangement nearly so well as an optical system against oil and dirt.
Initially, I found this part - AKL001-12E: http://www.nve.com/Downloads/gtsensor_catalog.pdf The "gear" and bias magnet would be easy to make and mount. I guess the tricky part is in dealing with the analog nature of the sensor, which means more than one or two components to wire, but no big deal. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.
