Electronica GS126 Optical Encoder Systems

The Electronica range of GS126 Glass Optical encoders implement a custom designed Opto-ASIC to enable it to operate in some of the harshest environments possible without compromising the quality of the output signals.

An ideal replacement or first fit encoder for manual machine tools, EDM, Wire-cut or applications where high resolution and accuracy are required at an affordable price.

Also see the MAGNA range of magnetic encoder systems.

Also available in GS126-11, a Glass Optical encoder specifically designed as a near direct replacement for legacy 40碌m period 11碌A optical encoders used both on older (Heidenhain) CNC applications and manual machine tools.
