Linear Encoder Systems

 

 List Price:   Prices vary by length 

 

MACHINEMATE INC has several linear feedback systems available. These systems all provide encoder signals (quadrature square wave, 5 VDC TTL), directly compatible with a MACHINEMATE CNC or other vendor CNC systems requiring encoder feedback.

 

The recent advancements in Digital Signal Processors (DSPs) along with high-speed analog-to-digital conversion ICs has allowed the Spherosyn technology to provide feedback for a wide range of motion control applications. This system has the environmental rating of IP67, or fully submersible, according to IEC 529; it exceeds NEMA type 6 rating. The system can withstand a shock of 100g and vibration of 30g. The scale is comprised of a tube that contains a column of high-precision, nickel-chrome ball bearings. The reader head contains a series of coil assemblies along with the supporting electronics. An electromagnetic field is generated by a drive current that interacts with the balls contained in the scale. The pickup coils detect the variations in the induced field which are then processed to generate the signals that vary in the encoder TTL square wave form. The ease of installation of this system has an added benefit since it does not require a machined surface for mounting.

 


 

Incremental linear feedback encoders, for travels of 2 inches to 40 inches (51mm to 1016mm)

 

The Microsyn* system uses a scale comprised of a carbon-fiber tube (0.257inches in diameter, or 6.5mm) that contains the column of ball bearings. The resolution of this system is down to 0.2microns. The data sheet is included (70 KB pdf, a single printed page).

 


 

Incremental linear feedback encoders, for travels of 4 inches to 453 inches (102mm to 11.5meters)

 

The Spherosyn* system uses a scale comprised of a 304 stainless steel tube (0.601inches in diameter, or 15.25mm) that contains the column of ball bearings. The resolution of this system is down to 0.5microns. The data sheet is included (70 KB pdf, a single printed page).

 


 

Distance-coded incremental linear feedback encoders, for travels of 4 inches to 365 inches (102mm to 9.3meters)

 

The Spherosyn* distance-coded linear feedback system uses a similar scale as above (304 stainless steel tube, 0.601inches in diameter, or 15.25mm) but the scale also contains uniquely spaced reference markers. These markers allow the encoder to mimic the distance-coded index marks that are generated by glass scales. The resolution of this system is down to 0.1microns. The data sheet is included (60 KB pdf, a single printed page).

All of the .pdf documents are presented in the Adobe pdf file format. If you do not have the Adobe Acrobat Reader, the software is free to download

 

For each document, it is advised that you right-click on the link and select Save Target As so that the file is downloaded to your PC for more convenient access. An approximate size (rounded up to nearest 10 KB) is included for each file to allow an estimate of the download time (that will depend on the speed of your internet connection). The data sheet files are rather large, so with a slow Internet connection a phone call to MACHINEMATE INC (920-907-0001) to get a faxed copy might be more efficient.
