DCRM - distance coded reference mark system
The DCRM system allows re-establishing the absolute position after traversing a short distance.
Overview
Introduction
The distance coded reference mark (DCRM) scale allows a measuring system to re-establish absolute position after traversing a short travel. It represents a great usage benefit especially on long axis (several tens of meters) in comparison with conventional reference marks, where re-establishing of absolute position can require traversing the entire axis.
The distance coding is created by having multiple reference marks individually spaced according to mathematical algorithm. Absolute position is known after traversing 2 successive reference marks.
Absolute position of 1st reference mark is calculated in controller electronics, based on relative distance between 2 neighbouring reference marks, direction of movement, basic increment, and magnetisation pole length. DCRM is currently available with 2 mm, 2.032 mm, and 5 mm pole lengths.
Features
- Customer selectable basic increment for optimal maximum length selection
- Available for MS10, MS12 and MS15 magnetic scales
- Ideal for long axis applications
- Compatible with standard RLS® LM10, LM13 and LM15 readheads

Accessories
Further information on the accessories can be found in the datasheet under the Documentation tab.
Applicator tool for magnetic scale
This applicator tool can be mounted in place of any RLS LM10 readhead and uses motion of the axis to apply the MS10 tape scale parallel to the guideway. The installation guide can be found in the Documentation tab.
Part number: LM10ASC00
End clamps for magnetic scale
The end clamps have been designed to anchor the ends of the MS magnetic scale. The installation guide can be found in the Documentation tab.
Part number: LM10ECL00
