Overview Linear Encoders

Product catalog summary
Overview
The document provides an in-depth analysis of TR-Electronic's linear encoders, emphasizing magnetostrictive technology for capturing linear movements and converting them into electrical signals. This technology relies on travel time delay measurement using a magnetostrictive wire and a non-contact permanent magnet as a position sensor.
Functional Description
Magnetostrictive linear encoders function by sending current pulses through a wire, creating a magnetic field. A torsion pulse is generated at the measurement point, traveling along the waveguide. The time difference between transmission and reception is converted into a distance-proportional signal, available as digital or analog output.
Product Features
The LMC55 model offers contact-free and wear-free scanning up to 20 meters, capable of measuring up to 30 positions simultaneously. It features a flat housing for easy installation and outputs data via interfaces like PROFIBus, EtherCAT, or CANopen. The system is reliable, with a protection class of IP65, and can be installed in any position.
Applications
These encoders are suitable for various applications, including pneumatic workstations, reel cutters, event technology, and transfer vehicles. They replace traditional systems like wire-actuated encoders and optical axes in profile cutting machines.
Modular System Explanation
The LMC55 system is modular, consisting of a master module and slave modules. The system can be extended by adding more modules, allowing for flexible measurement lengths. The teaching process ensures correct configuration before operation.
LMR70 Model
The LMR70 is a triple-redundant linear absolute measurement system designed for challenging environments, such as power plants. It features three independent systems within one tube, providing long-term availability and reliability. The system is compatible with hydraulic cylinders and withstands pressures up to 600 bar.
Technical Specifications
The document includes detailed specifications for various models, such as LA46, LMRI46, and LMR48, covering aspects like range, resolution, linearity defect, reproducibility, and protection class. The encoders are available with multiple interfaces and are designed for easy integration into existing systems.
Ordering Information
Specific product codes and configurations are provided for ordering, including details on measurement length, tube length, and resolution.

This measuring principle is based on a travel time delay measurement. Current pulses are sent through a magnetostrictive wire, positioned inside a protective tube, creating a ring-shaped magnetic field around the wire. A non-contact permanent...

Contact-Free and Wear-Free scanning up to 20 m – LMC55 Measure reliably over long distances Wire-actuated encoders are subject to wear, and laser measuring systems cannot acquire several positions simultaneously in the same clear width. Magnetic tapes are susceptible to ferromagnetic chips, position marks read optically with readers can become soiled, magnetostrictive measuring systems are limited in their measuring length, and glass scales are unaffordable with increasing measurement lengths. With LMC55 we have closed this gap: up to 30 positions are acquired simultaneously. The moving part...

Example: Profibus The measuring system has two LEDs. A green LED (Bus run) to display status information and a red LED (Bus fail) to display errors. When the measuring system starts up, both LEDs flash briefly. The display then depends on the operating status of the measuring system. Can be extended at any time - individual measuring lengths in stock LED, red Simply keep individual components in stock. If a replacement is required, you will have the replacement modules immediately available. You can replace the necessary modules and then carry out the repair unhurriedly - also resulting in minimal...

Three Measuring Systems in One – LMR70 Triple-redundant linear absolute measurement system provides longterm availability even with difficult access What sounds like a child‘s naive wish is a clear demand for automated solutions where the technical facilities are extremely difficult to access. Applications in power plant technology and in locks and weirs “sink“ the technology into machine rooms below the waterline. They are therefore difficult to access. Even the long service life that has been established in this industry is not long enough for system lifecycles that last several years without...
