Heidenhain Exposed linear encoder
The Lida 400 linear encoder series has been redesigned to be mechanically compatible with the previous Lida 400 family. Scanning units are interchangeable with older graduations. Still maintaining a 20-micron graduation, and interpolation available up to 100 times from the scanning unit, the exposed encoder system can have a resolution of 50 nm and accuracies to ±1 micron. A new multi-colored status LED on the side of the scanning unit indicates the signal levels during installation. The LED can be used as a quick status check of the encoder to determine functionality. It also indicates the reference mark signal quality.
