Linear encoder system offers large mounting tolerances

Heidenhain has introduced the LIP 6000 miniature linear encoder system, comprising a scanning unit and glass scale. It has the capability to measure to 2-nm resolution with a high speed of 13 FPS at long lengths of scale.

The encoder was developed with large mounting tolerances, small interpolation error, and low noise levels, making it suitable for use in machine feedback applications in which very constant speed control is needed or high position stability at standstill is important.

The scanning unit HSP (Heidenhain Signal Processor) 1.0 ASIC overcomes contamination on the glass without the loss of accuracy by amplifying the LED light source instead of amplifying the electrical signals that lead to noisy outputs.
