4.5.1 HIWIN-MAGIC
The HIWIN-MAGIC distance measuring system is used in the linear tables HT-L for incremental distance measurement. The
output signals can be either analogue or digital. The HIWIN-MAGIC distance measuring system consists of the encoder (Fig.
4.4) and the magnetic scale (Fig. 4.5) as the measurement standard. It is assembled prior to delivery.

MAGIC magnetic scale
The measuring scale of the magnetic measuring systems may not be subjected to any strong magnetic fields
(keep it well away from permanent magnets!). Strong shocks (e.g. hammer blows) can also damage the mag-
netization of the measuring scale. The system is not suitable for environments where there is magnetic dust
(e.g. graphite dust). These things can falsify the encoder signal or damage the distance measuring system.
