Asahi Angle Sensor, EM-3242

| |
|
The New Asahi –Kasei EMD Non Contact 360 Degree Angle Sensor- EM-3242
|
The improved Asahi EM-3242 Angle Sensor will be available in January 2008 and will replace the existing EM-3241 sensor.
The improved version will be the same size and in the same 6 pin package, however it will have a different pin out than
the EM-3241. For initial development and early product evaluation the EM-3241 is an excellent choice and will be available
in limited quanties until May 2008.
All performance parameters of the new EM-3242 will be the same or better than the EM-3241 except for the speed performance
which will be slightly slower. Compatibility between the two versions will be excellent except for the IC pin out.
Changes to the pin out are shown below as well a summary table of the performance characteristics between the two parts.
