1 Data sheet LM0D8_0 6 th November 07 TRS track system Designed for applications which demand that the scale be removed easily, the track system consists of aluminium guide rails available in m and m sections and a scale clamp element. It securely retains the magnetic scale whilst allowing it to expand and contract freely. The scale clamp provides a fixed point from which the MS scale can expand. If damaged, the scale can be pulled out of the guide rails and replaced even where access is limited, thus reducing machine downtime. This feature also makes the system ideal for large machines that need to be sectioned for transportation. The system also allows the user to easily join the ends of two magnetic scales and reach lengths longer than 00 m. The design of the track section allows installation next to most standard guide rails or freely on any surface. Therefore it is suitable for many applications, such as automated assembly equipment, packaging equipment, printing and other machines that require the scale to be installed/removed for transit, or simply for any application where thermal expansion of the scale must be independent of the machine structure. luminium carrier for easy magnetic scale refitting llows the scale to freely expand with almost zero hysteresis llows joining the ends of magnetic scales to reach lengths longer than 00 m vailable section lengths: m, m Two different installation methods to fit your application Compatible with all RLS readheads and magnetic scales associate company
