For typical appli**ions on manual **hine tools such as milling **hines or lathes, display steps of 10 µm or 5 µm are suffi cient. Such display steps are provided by the LS 300 and LS 600 series linear encoders with an accuracy grade of ± 10 µm per meter tr**erse.

LS 388CThe LS 1679 has been specially developed for press brakes. The basis for its high accuracy and repeatability is its precise glass scale and high-quality integral bearing. Thanks to the material of its steel track and steel roller bearing **ponent pair it is very robust. There are many variants for connection to the **hine frame, whereby the ball coupling offers the most degrees of freedom. Besides the standard resolution with 5 µm measuring step there is also a variant with 1 µm. For perfect mounting to the two C-columns there are variants with rightward and leftward cable outlets.
