HEIDENHAIN's New LS Linear Scales Offer High Level Scanning Technology

SCHAUMBURG, IL - (October 2006) - Equipped with advanced Single-Field Scanning technology and incorporating all the latest developments in linear measurement technology, HEIDENHAIN is now making available their latest sealed linear encoders called the LS XX7 Series. These new scales are available up to 3m in length, come in two different mechanical profiles and offer unparalleled resistance to contamination and vibration making them particularly useful in dynamic machine tool applications.

This new single-field scanning technology provides significant encoder advantages regarding the tolerance to contamination and to electromagnetic noise sources. Along with this improved signal stability, single-field scanning also has proven to improve signal quality providing a typical output signal error of ± 1 % within one signal period.

Along with offering an improved encoder, simple mounting methods are standard with these HEIDENHAIN LS linear encoders in order to incorporate them into a wide variety of applications. Encoders of the LS 400 series can now utilize a universal mounting spar when required which allows for a cable outlet to the left or right. Available accessories also include clamps as an alternative that are mounted at fixed intervals along the measuring length to provide additional support.

Encoders of the LS 100 series have a left and right cable outlet directly on the scanning unit. The unused socket connector is protected by a cap and both encoders of the new series utilize the same cable assembly.
