CAUTION!
Danger through non-conventional use!
Non-intended use and non-observance of this operating manual can lead to dangerous situations.
Therefore:
Only use the device as described
Strictly follow the instructions of this manual
Avoid in particular:
Remodeling, refitting or changing of the construction or single components with the intention to alter the
functionality or scope of the device.
CAUTION!
Transport the package (box, palette etc.) professionally.
Do not throw, hit or fold it.
NOTE!
Claim any damage immediately after recognizing it.
The claims for damage must be filed in the lawful reclaim periods.
IMPORTANT!
When storing the coded rod, it must be explicitly ensured that it is not placed in the vicinity of foreign magnets
(refer also to section “Technical Data” 6.3„Environmental Conditions“).
4.7 Conventional Use
The ELGO-device is only conceived for the conventional use described in this manual.
The ELGO MTM-A-000 length measuring system only serves to measure positions, lengths and/or speeds.
Claims resulting from damages due to non-conventional use are not possible.
Only the operator is liable for damages caused by non-conventional use.

5 Product Features
The MTM-A-000 measuring system is based on the physical principle of magnetism and is used for a highprecision determination of the position, the moved distance and/or the speed. Based on this wear-free and contactless absolute measuring system, MTM-A-000 is suitable for fixed round rod profiles - for example for nonrotating piston rods of hydraulic cylinders in mobile automation.
The system consists of the following components:
Round rod resp. piston rod (provided by the customer for absolute coding by ELGO)
Application related sensor system (ELGO made)
Mechanical accessories for sensor adaptation on request
5.1 Principle of Scanning
In order to determine the absolute position, the basis of the
magnetic MTM-A-000 linear encoder consists of a scanning technology, which scans the magnetically coded round
rod contactless and completely wear-free.
The measured value is processed by the internal evaluation
electronics and is available either via a CANopen interface
or as an analog output signal (mA or Volt). From here it
can be further processed by the subsequent electronics.
5.2 The absolute Measuring Principle
The absolute measuring principle ensures maximum safety, as the current position value is always present. Even
in the event of a power failure, no data is lost. The measuring system only needs to be referenced once by learning the upper and lower position (see 8.4 Calibration of the Measuring Range).
Figure 1: Example of an absolute coded round rod track
5.3 Available Output Signals
Depending on the ordered interface option (see type designation 11) the sampled signal information is converted by the internal evaluation electronics into one of the following output signals:
Interface option CA0 CANopen standard interface according to DS406 (encoder profile)
Interface option I20 Analog 12 bit output signal (0 … 20 mA), proportional to the measured value
Interface option I24 Analog 12 bit output signal (4 … 20 mA), proportional to the measured value
Interface option V04 Analog 12 bit output signal (0.5 … 4.5 V), proportional to the measured value
Interface option V10 Analog 12 bit output signal (0 … 10 V), proportional to the measured value
More information can be found in chapter 9 Connections and Interfaces.
